5\times 2+5x\left(-\frac{4}{5}\right)=5\times 3
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5x, the least common multiple of x,5.
10+5x\left(-\frac{4}{5}\right)=5\times 3
Multiply 5 and 2 to get 10.
10-4x=5\times 3
Cancel out 5 and 5.
10-4x=15
Multiply 5 and 3 to get 15.
-4x=15-10
Subtract 10 from both sides.
-4x=5
Subtract 10 from 15 to get 5.
x=\frac{5}{-4}
Divide both sides by -4.
x=-\frac{5}{4}
Fraction \frac{5}{-4} can be rewritten as -\frac{5}{4} by extracting the negative sign.
