3+5(c+3)=−17

3+(5)(c)+(5)(3)=−17(Distribute)

3+5c+15=−17

(5c)+(3+15)=−17(Combine Like Terms)

5c+18=−17

Subtract 18 from both sides.

5c+18−18=−17−18

5c=−35

Divide both sides by 5.

5c/5=−35/5

c=−7

3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like:
5(c + 3) = -17 - 3
Second, simplify -17 - 3 to get -20. / Your problem should look like:
5(c + 3) = -20
Third, divide both sides by 5. / Your problem should look like:
c + 3 = -(20)/(5)
Fourth, simplify
(20)/(5) to 4. / Your problem should look like:
c + 3 = -4
Fifth, subtract 3 from both sides. / Your problem should look like:
c = -4 - 3
Sixth, simplify -4 - 3 to get -7. / Your problem should look like:
c = -7

Answer: c = -7
