Substitute what you know y is equal to into the equation:
y = x + 2
3/2x - 2 = x + 2

Then you can simplify your equation by multiplying both sides by 2 to eliminate the fraction which will give you:

3x - 4 = 2x + 4

Add the -4 to the other side to get 8 and subtract the 2x from the 3x so you have:

x = 8 Now solve for y by substituting your value for x into the other equation:
y = 3/2(8) - 2 Simplify by combining your numbers and you get:
y = 10 Check your answer by substituting y and x into the original equation:
(10) = (8) - 2
Correctly done! So your answers are x = 8 and y = 10
