7Y = 33-4Y ( add 4Y to both sides of equation )
11Y = 33 ( divide both sides of equation by 11 )
Y = 3

5y+8=7y 2y=8 y=4
If: y = x -2 and 7y -4x = 10 Then: x = 8 and y = 6
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
