5x + 3 = -12 5x =-12-3 =-15 x = -3
5x - 4x = 13 - 3 ie x = 10
Add: 5x - y + x + y + 8 + 10 ie 6x = 18 so x = 3 and y = 7
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 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.
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
5x plus 3 does equal 3 plus 5x; commutative law.
33
Your question is actually: "What is 'x' if [18 = 3 + 5x] ?"18 = 3 + 5xSubtract 3 from each side of the equation:15 = 5xDivide each side by 5:3 = x
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x + 3 = -12 5x =-12-3 =-15 x = -3
5x - 4x = 13 - 3 ie x = 10
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
-4x + 3 = -5x + 3add 5x to each sidex + 3 = 3subtract three from each sidex = 0
Do you mean: 5x + 9 - 7x + 6 = x - 18 If so, you can solve this question at this manner: -2x + 15 = x - 18 3x = -3 x = -1
3 + 5x = 38 -> 5x = 35 -> x = 7
