Question 590599
{{{(2/5)x+7=9}}} Start with the given equation.



{{{5((2/cross(5))x+7)=5(9)}}} Multiply both sides by the LCD {{{5}}} to clear any fractions.



{{{2x+35=45}}} Distribute and multiply.



{{{2x=45-35}}} Subtract {{{35}}} from both sides.



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



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



{{{x=5}}} Reduce.
