5x+12=10\times 3x-40
Multiply both sides of the equation by 20, the least common multiple of 4,5,2.
5x+12=30x-40
Multiply 10 and 3 to get 30.
5x+12-30x=-40
Subtract 30x from both sides.
-25x+12=-40
Combine 5x and -30x to get -25x.
-25x=-40-12
Subtract 12 from both sides.
-25x=-52
Subtract 12 from -40 to get -52.
x=\frac{-52}{-25}
Divide both sides by -25.
x=\frac{52}{25}
Fraction \frac{-52}{-25} can be simplified to \frac{52}{25} by removing the negative sign from both the numerator and the denominator.
