2x - 3 - 8 = 1. 2x - 11 = 1. 2x = 12.x = 6!
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
2X + 7 = 5X + 16 subtract 2X from both sides 7 = 3X + 16 subtract 16 from both sides -9 = 3X divide both sides by 3 -3 = X check 2(-3) + 7 = 5(-3) + 16 1 = 1 checks
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
-6x2 + 17x -12. To get the solution, we set up the formula as follows: (2x - 3) * (4 - 3x) Then we multiply each of the components as follows: (2x * 4) + (2x * -3x) + (-3 * 4) + (-3 * -3x) Then we simplify as follows: 8x + -6x2 + -12 + 9x -6x2 + 17x + -12 -6x2 + 17x -12
