Question 158170
"Seven times the difference of 7 and a number gives 70" translates to {{{7(7-x)=70}}}



{{{7(7-x)=70}}} Start with the translated equation.



{{{49-7x=70}}} Distribute.



{{{-7x=70-49}}} Subtract {{{49}}} from both sides.



{{{-7x=21}}} Combine like terms on the right side.



{{{x=(21)/(-7)}}} Divide both sides by {{{-7}}} to isolate {{{x}}}.



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