5\times 3+10x\left(-\frac{7}{5}\right)=2\times 4+10x\left(-\frac{5}{2}\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10x, the least common multiple of 2x,5,5x,2.
15+10x\left(-\frac{7}{5}\right)=2\times 4+10x\left(-\frac{5}{2}\right)
Multiply 5 and 3 to get 15.
15-14x=2\times 4+10x\left(-\frac{5}{2}\right)
Multiply 10 and -\frac{7}{5} to get -14.
15-14x=8+10x\left(-\frac{5}{2}\right)
Multiply 2 and 4 to get 8.
15-14x=8-25x
Multiply 10 and -\frac{5}{2} to get -25.
15-14x+25x=8
Add 25x to both sides.
15+11x=8
Combine -14x and 25x to get 11x.
11x=8-15
Subtract 15 from both sides.
11x=-7
Subtract 15 from 8 to get -7.
x=\frac{-7}{11}
Divide both sides by 11.
x=-\frac{7}{11}
Fraction \frac{-7}{11} can be rewritten as -\frac{7}{11} by extracting the negative sign.
