-15x - 3(5x-1) = 3 [input y] -15x - 15x - 3 = 3 [distribute 3 over 5x and -1] -30x - 3 = 3 [combine like terms] -30x = 6 [add 3 to eliminate the negative] x = [tex] \frac{6}{-30} [/tex] [divide by -30 to get x alone] x = [tex] \frac{1}{-5} [/tex] [reduce the fraction]
Hopefully this is helpful enough to get you to your answer
