Question 191773


{{{(3/10)x-2/5=-1}}} Start with the given equation.



{{{cross(10)((3/cross(10))x)-cross(10)^2(2/cross(5))=10(-1)}}} Multiply EVERY term by the LCD {{{10}}} to clear any fractions.



{{{3x-4=-10}}} Multiply.



{{{3x=-10+4}}} Add {{{4}}} to both sides.



{{{3x=-6}}} Combine like terms on the right side.



{{{x=(-6)/(3)}}} Divide both sides by {{{3}}} to isolate {{{x}}}.



{{{x=-2}}} Reduce.

Answer:


So the answer is {{{x=-2}}}
