Answer:
4)x= g-c
5)x =u+k
6)x = g-c
7)
8)
9)
10)
11)
12)
13)a= d -r + c
14)
Step-by-step explanation:
4) g= c+x
x= g-c
5) u=x-k
x =u+k
6)g = c+x
x = g-c
7) 
8) g=xc

9) 12am = 4

10)-3x+2c = -3
2c = -3 +3x
2c +3 = 3x

11) am= n+p

12)
13)a-c = d-r
a= d -r + c
14)xm= np

Answer:
2(3x+6) = 6x+12
3(2x-6) = 6x-18
6x+12=6x-18
Subtract 12 from 18, which gives you:
6x=6x-6
Subtract the 6x on the opposite side of the equal side, and your answer is: x = -6
