3 - x = x - 1
Add x to both sides: 3 = 2x - 1
add 1 to both sides: 4 = 2x
Divide both sides by 2: 2 = x
6x = 1 x = 1/6
2x - 3 - 8 = 1. 2x - 11 = 1. 2x = 12.x = 6!
x + (3 - 2) = -5Clear the parentheses on the left side:x + 1 = -5Subtract 1 from each side:x = -6That's the whole set of solutions.There's only one solution.
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
