3x=10x+36
Multiply both sides of the equation by 15, the least common multiple of 5,3.
3x-10x=36
Subtract 10x from both sides.
-7x=36
Combine 3x and -10x to get -7x.
x=\frac{36}{-7}
Divide both sides by -7.
x=-\frac{36}{7}
Fraction \frac{36}{-7} can be rewritten as -\frac{36}{7} by extracting the negative sign.
