Question 321509


{{{-2u+2=4}}} Start with the given equation.



{{{-2u=4-2}}} Subtract {{{2}}} from both sides.



{{{-2u=2}}} Combine like terms on the right side.



{{{u=(2)/(-2)}}} Divide both sides by {{{-2}}} to isolate {{{u}}}.



{{{u=-1}}} Reduce.

Answer:


So the solution is {{{u=-1}}} which means that {{{5u+4=5(-1)+4=-5+4=-1}}}
