5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
8x-7 plus 2x equals 6 plus 5x plus 2?

30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6
5x=4012y=84124
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
3 + 5x = 38 -> 5x = 35 -> x = 7

-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.
