5x - 4x = 13 - 3 ie x = 10
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
5x + 3 = 18 Subtract 3 from both sides: 5x = 15 Divide by 5: x = 3.
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.
