-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
-5x-5=25 -5x=30 x=-6
30.
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6
5x=30...then x=30/5. So X=6.
(5x-10)(x+3)
= (5x - 30) + (3 - 7) = 5x - 30 - 4 = 5x - 34
4x+12-5x-30=-x-18
30
5x+2y = 30 2y = -5x+30 y = -2.5x+15 Therfore the slope is 2.5 and y the intercept is 15.
