How would you solve this multi-step equation? Would you combine like terms first?
-7x+x=-15+3-4x-8x
Solve for x:
-6 x = -12-12 x
Add 12 x to both sides:
12 x-6 x = (12 x-12 x)-12
12 x-12 x = 0:
12 x-6 x = -12
12 x-6 x = 6 x:
6 x = -12
Divide both sides of 6 x = -12 by 6:
(6 x)/6 = (-12)/6
6/6 = 1:
x = (-12)/6
The gcd of -12 and 6 is 6, so (-12)/6 = (6 (-2))/(6×1) = 6/6×-2 = -2:
Answer: |x = -2
