Answer:

c = 9

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
