The ans is choice D. since there nothing under 5x, imagine there is a 1 under. After that, you can simply cross multiply, so it would be 1(6+8x)= 2(5x). 6+8x= 10x now combine like terms so subtract 8x from both sides and divide 6 by 2 and you will get 3

How to solve 3+5 (c+3)=-17
BlackZzzverrR [31]
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 =  -\frac{20}{5}
Fourth, simplify \frac{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
