8x-7 plus 2x equals 6 plus 5x plus 2?
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x + 2 = 4x -1 2x = 3 x = 1.5
4x + 2 = 2x + 5 Subtract through by 2x 2x + 2 = 5 Subtract through by 2 2x = 3 Divide through by 2 x = 1.5 ■
6x + 3 = 2x + 5 4x = 2 x=1/2
x²+2x-15=0 x1=-2/2 - Square root of ((2/2)²+15) x1=-1-4 x1=-5 x2=-2/2 + Square root of ((2/2)²+15) x2=-1+4 x2=3
8x-7 plus 2x equals 6 plus 5x plus 2?
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2 plus 1-x divided by.
2x+2=x+5 x=3
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
