15x minus 8=minus 180 3x+8=24
6x-2=x+135x=15x=3
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
you just add 6x+9x to get 15x then minus 25 from 18 to get -7 thus the answer will be 15x-7
