Answer:
c = -17
Step-by-step explanation:
<u>→Distribute the 7 to (-7c - 19):</u>
3 - 7c - 20c = -49c - 133 + 14c
<u>→Add like terms (-7c and -20c, -49c and 14c):</u>
3 - 27c = -35c - 133
<u>→Add 35c to both sides:</u>
3 + 8c = -133
<u>→Subtract 3 from both sides:</u>
8c = -136
<u>→Divide both sides by 8:</u>
c = -17
