Answer: 4(9a-4) and x = 18
Explanation:
36a - 16 a common factor in this is 4 so if we factor out 4 we would get
4(9a-4)
1/2x - 7 = 1/3(x-12) we would distribute out the 1/3 so 1/3x and 1/3 x - 12 which would simply into 4
1/2x - 7 = 1/3x - 4 get the x's into one side so subtract 1/3x and add 7 on both sides
1/2x - 1/3x = 3 --- multiply 1/2x with 3/3 and 1/3x with 2/2
3/6x - 2/6x = 3
1/6x = 3 --- isolate x by multiplying 6 on both sides
x = 18
