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
2x - 3 - 8 = 1. 2x - 11 = 1. 2x = 12.x = 6!
x = 5
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
7 and (-3/2)
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
4(2x-3)+7=8x8x-12+7=8x-8x..........-8x-12+7=0+12.....+127=12-7...-7No Solution:0≠54(2x-3+7)=8x8x-12+28=8x-8x............8x-12+28=0+12.......+1228=12-28...-28No Solution: 0≠-16
(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
2X - 3 = 18X -2X -2X ( Subtract 2X from both sides ) ------------------ -3 = 16X ( Divide both sides by 16 ) -------------------- so, X = -3/16 OR -.1875
Blue is not a solution.
2x2 - x - 15 = 0(2x + 5) (x - 3) = 0[2x + 5 = 0] and [x - 3 = 0]x = -5/2 and x = 3{-2.5, 3}
2 is a solution of the equation, but not if it's an inequality.
