Answer:
x = 2 y = 4
Step-by-step explanation:
y = 3x - 2
x = y - 2
Plug in the equation of x into the first equation and solve for y.
y = 3x - 2
y = 3(y - 2) - 2 Multiply out
y = 3y - 6 - 2
y = 3y - 8 Add 8 to each side
y + 8 = 3y - 8 + 8 8 cancels on the right
y + 8 = 3y Subtract y from each side
y - y + 8 = 3y - y The y on the left cancels
8 = 2y Divide each side by 2
8/2 = 2y/2 2 on the right cancels because 2/2 = 1
8/2 = y
4 = y
Now plug your answer into the 2nd equation given to solve for x.
x = y - 2
x = 4 - 2
x = 2
