Question 352273
# 1


{{{8(7-y)=-21}}} Start with the given equation.



{{{56-8y=-21}}} Distribute.



{{{-8y=-21-56}}} Subtract {{{56}}} from both sides.



{{{-8y=-77}}} Combine like terms on the right side.



{{{y=(-77)/(-8)}}} Divide both sides by {{{-8}}} to isolate {{{y}}}.



{{{y=77/8}}} Reduce.



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


Answer:


So the answer is {{{y=77/8}}}

# 2





{{{-2(5+6m)+16=-90}}} Start with the given equation.



{{{-10-12m+16=-90}}} Distribute.



{{{-12m+6=-90}}} Combine like terms on the left side.



{{{-12m=-90-6}}} Subtract {{{6}}} from both sides.



{{{-12m=-96}}} Combine like terms on the right side.



{{{m=(-96)/(-12)}}} Divide both sides by {{{-12}}} to isolate {{{m}}}.



{{{m=8}}} Reduce.

Answer:


So the answer is {{{m=8}}}
