\left(5x+2\right)\left(4-3\right)=\left(2x-5\right)\times 7
Variable x cannot be equal to any of the values -\frac{2}{5},\frac{5}{2} since division by zero is not defined. Multiply both sides of the equation by \left(2x-5\right)\left(5x+2\right), the least common multiple of 2x-5,5x+2.
\left(5x+2\right)\times 1=\left(2x-5\right)\times 7
Subtract 3 from 4 to get 1.
5x+2=\left(2x-5\right)\times 7
Use the distributive property to multiply 5x+2 by 1.
5x+2=14x-35
Use the distributive property to multiply 2x-5 by 7.
5x+2-14x=-35
Subtract 14x from both sides.
-9x+2=-35
Combine 5x and -14x to get -9x.
-9x=-35-2
Subtract 2 from both sides.
-9x=-37
Subtract 2 from -35 to get -37.
x=\frac{-37}{-9}
Divide both sides by -9.
x=\frac{37}{9}
Fraction \frac{-37}{-9} can be simplified to \frac{37}{9} by removing the negative sign from both the numerator and the denominator.
