2x + 2 + 5x = 23 2x +5x = 23 -2 7x = 21 X = 3
5x plus 3 does equal 3 plus 5x; commutative law.
7x = 21 x = 3
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
5x-6+23-7x 5x-7x+23-6 (rearranged) -2x+17 (simplification).
3 + 5x is the simplest expression of this problem.
3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
(5x+3)(5x+3) x=(-3/5)
It is 5x - 9.
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x + 3 - 4 + 4x = 9x -1
