Answer:

Hi, the correct answer to your question is Y,X would be (29,11)

ONE SOLUTION

Explanation:

First you have to... solve for y

Y equals 2x+7

Next you have to use the variable y and put in into an equation.

2x+7 - 3x = -4 (Also) :) - x = -11

Now you have to solve the equation for the variable x

Which will be 11 (x will be 11)

Finally you have to use x to solve for y

2(11)+7 = 29

Now we have 11 and 29 so the answer to your question will be

= (29,11)

Also this means it has one solution

Btw this is a linear equation...

Hope this helps you! :)
