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
