Answer:
c = 9
Step-by-step explanation:
2(3c+6)+7−5×1+2−1+9c=69+4c+5c
Add 12 and 7 to get 19.
6c+19−5×1+2−1+9c=69+4c+5c
Multiply 5 and 1 to get 5.
6c+19−5+2−1+9c=69+4c+5c
Subtract 5 from 19 to get 14.
6c+14+2−1+9c=69+4c+5c
Add 14 and 2 to get 16.
6c+16−1+9c=69+4c+5c
Subtract 1 from 16 to get 15.
6c+15+9c=69+4c+5c
Combine 6c and 9c to get 15c.
15c+15=69+4c+5c
Combine 4c and 5c to get 9c.
15c+15=69+9c
Subtract 9c from both sides.
15c+15−9c=69
Combine 15c and −9c to get 6c.
6c+15=69
Subtract 15 from both sides.
6c=69−15
Subtract 15 from 69 to get 54.
6c=54
Divide both sides by 6.
c = 54/6
Divide :)
c = 9
