3x+15=5\times 2x
Multiply both sides of the equation by 15, the least common multiple of 5,3.
3x+15=10x
Multiply 5 and 2 to get 10.
3x+15-10x=0
Subtract 10x from both sides.
-7x+15=0
Combine 3x and -10x to get -7x.
-7x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{-7}
Divide both sides by -7.
x=\frac{15}{7}
Fraction \frac{-15}{-7} can be simplified to \frac{15}{7} by removing the negative sign from both the numerator and the denominator.
