Question

Solve: -4(x + 1) - 3 = -3(x - 4)

Answer 1

distribute first. times the number on the outside of the parenthisis by everything inside them
-4(x + 1) - 3 = -3(x - 4) ----> -4x -4 -3 = -3x +12
combine like terms
-4x-7 = -3x +12
get one variable by itself, its easier to add in this one, so add the 7. you could subtract the 12 from both sides too if you like
-4x = -3x +19
now lets add the -3x to both sides!
-x = 19
the x cant be negitive in the answer, so divide by -1
youre answer is x=-19
