The system of **equations **are solved using **substitution **method and there are infinite number of solutions

**Equations **are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an **equation**. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the **equation **be represented as A

To solve the given system of **equations **using the **substitution **method, we can follow these steps:

Step 1:

Solve one of the **equations **for one variable in terms of the other variable.

Let's solve the first equation, y - 3x = 7, for y in terms of x:

y = 3x + 7

Step 2:

**Substitute **the **expression **for the solved variable into the other equation.

Substitute the expression for y from step 1, which is 3x + 7, into the second equation, 21 + 9x = 3y:

21 + 9x = 3(3x + 7)

Step 3:

Simplify and solve for the remaining variable.

Now we can simplify the **equation **and solve for x:

21 + 9x = 9x + 21

0 = 0

Hence , resulting **equation **is a true statement, 0 = 0, which means that the system of equations is dependent and there are an **infinite **number of solutions.

The answer is B

let me show my answer

-3x+y=7;9x+21=3y

Solve -3x+y=7 for y

Add 3x to both sides

-3x+y+3x=7+3x

y=3x+7

Substitute 3x+7 for y in 9x+21 =3y

9x+21=3y

9x+21=3(3x+7)

Simplify both sides of the equation

9x+21=9x+21

Add -9x to both sides

9x+21+-9x=9x+21+-9x

21=21

Add -21 to both sides

21+-21=21+-21

0=0

Answer : B , Infinitely many solutions

I hope that's help !

Have a great day !

Put the number on the right side of the chart into where x is and solve the problem than once you get your answer put it into the chart next to which number you inserted into for x

The person above me is correct ^

(5/8):(1/4)= 5/8 • 4= 20/8=5/2 = 2 and 1/2

5/8/1/4

=5/8*4/1

=5/2

20 charrr

=5/8*4/1

=5/2

Ok, so the first thing you are going to do is change the division sign Into a multiplication sign. Then, you are going to flip 1/9. That will become 9/1.

So you would have to write it down 5/6÷1/9 so you would have to do kcf it stands for keep change flip so you would keep 5/6 and change the division sign into a multiplication because the opposite operation of division is multiplication then you would do flip so you would have to flip 1/9 to 9/1. Now your operation should look like this 5/6 times 9/1 and you will get 45/6 so you would divide them so 45÷6 is 7 3/6 and then you would simplify it and get 7 1/2

Do 8 divided by 9 on a calculator. You get .88

.888 repeating or rounded to .89

21*3.86/0.207

anyone knw the estimate for this?
