Question 198875


{{{18-3(5-x)=x-7}}} Start with the given equation.



{{{18-15+3x=x-7}}} Distribute.



{{{3x+3=x-7}}} Combine like terms on the left side.



{{{3x=x-7-3}}} Subtract {{{3}}} from both sides.



{{{3x-x=-7-3}}} Subtract {{{x}}} from both sides.



{{{2x=-7-3}}} Combine like terms on the left side.



{{{2x=-10}}} Combine like terms on the right side.



{{{x=(-10)/(2)}}} Divide both sides by {{{2}}} to isolate {{{x}}}.



{{{x=-5}}} Reduce.

Answer:


So the solution is {{{x=-5}}}
