{{{5x+7=-8}}} Start with the given equation.



{{{5x=-8-7}}} Subtract {{{7}}} from both sides.



{{{5x=-15}}} Combine like terms on the right side.



{{{x=(-15)/(5)}}} Divide both sides by {{{5}}} to isolate {{{x}}}.



{{{x=-3}}} Reduce.



----------------------------------------------------------------------


Answer:


So the solution is {{{x=-3}}} 



So you are correct. Good job.



Here's how you check your answer:



{{{5x+7=-8}}} Start with the given equation.



{{{5(-3)+7=-8}}} Plug in {{{x=-3}}}



{{{-15+7=-8}}} Multiply 5 and -3 to get -15



{{{-8=-8}}} Add -15 to 7 to get -8



Since the equation is true, this verifies the answer.
