4x = 3y - 7; x = 4,5,6

Question

Solve each equation for y. Then find the value of y for each value of x.

Answer 1

To solve an equation for y means to isolate y.

4x = 3y...Divide both sides by 3 to get (4x)/3 = y

So the equation solved for y is

y = (4x)/3

When x = 4, y = (4*4)/3= 16/3

When x = 5, y = (4*5)/3 = 20/3

When x = 6 y = (4*6)/3 = 24/3 = 8

Answer 2

This problem first wants us to solve this equation for y:

4x = 3y - 7

+7 +7

4x + 7 = 3y

3 3

Now, to solve for y we are going to plug in all of the values they give us for x:

4(4)+ 7 = y

3

23/3 = y

4(5) + 7 = y

3

9 = y

4(6) + 7 = y

3

31/3 = y
