\left(x-2\right)\times 5-\left(2x-5\right)\times 4=0
Variable x cannot be equal to any of the values 2,\frac{5}{2} since division by zero is not defined. Multiply both sides of the equation by \left(x-2\right)\left(2x-5\right), the least common multiple of 2x-5,x-2.
5x-10-\left(2x-5\right)\times 4=0
Use the distributive property to multiply x-2 by 5.
5x-10-\left(8x-20\right)=0
Use the distributive property to multiply 2x-5 by 4.
5x-10-8x+20=0
To find the opposite of 8x-20, find the opposite of each term.
-3x-10+20=0
Combine 5x and -8x to get -3x.
-3x+10=0
Add -10 and 20 to get 10.
-3x=-10
Subtract 10 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-10}{-3}
Divide both sides by -3.
x=\frac{10}{3}
Fraction \frac{-10}{-3} can be simplified to \frac{10}{3} by removing the negative sign from both the numerator and the denominator.
