2\times 2x+5\times 2=5\times 5x-40\times \frac{3}{5}
Multiply both sides of the equation by 10, the least common multiple of 5,2.
4x+5\times 2=5\times 5x-40\times \frac{3}{5}
Multiply 2 and 2 to get 4.
4x+10=5\times 5x-40\times \frac{3}{5}
Multiply 5 and 2 to get 10.
4x+10=25x-40\times \frac{3}{5}
Multiply 5 and 5 to get 25.
4x+10=25x-\frac{40\times 3}{5}
Express 40\times \frac{3}{5} as a single fraction.
4x+10=25x-\frac{120}{5}
Multiply 40 and 3 to get 120.
4x+10=25x-24
Divide 120 by 5 to get 24.
4x+10-25x=-24
Subtract 25x from both sides.
-21x+10=-24
Combine 4x and -25x to get -21x.
-21x=-24-10
Subtract 10 from both sides.
-21x=-34
Subtract 10 from -24 to get -34.
x=\frac{-34}{-21}
Divide both sides by -21.
x=\frac{34}{21}
Fraction \frac{-34}{-21} can be simplified to \frac{34}{21} by removing the negative sign from both the numerator and the denominator.
