6\left(x-4\right)-15\left(x+6\right)=10\left(x+5\right)-15
Multiply both sides of the equation by 30, the least common multiple of 5,2,3.
6x-24-15\left(x+6\right)=10\left(x+5\right)-15
Use the distributive property to multiply 6 by x-4.
6x-24-15x-90=10\left(x+5\right)-15
Use the distributive property to multiply -15 by x+6.
-9x-24-90=10\left(x+5\right)-15
Combine 6x and -15x to get -9x.
-9x-114=10\left(x+5\right)-15
Subtract 90 from -24 to get -114.
-9x-114=10x+50-15
Use the distributive property to multiply 10 by x+5.
-9x-114=10x+35
Subtract 15 from 50 to get 35.
-9x-114-10x=35
Subtract 10x from both sides.
-19x-114=35
Combine -9x and -10x to get -19x.
-19x=35+114
Add 114 to both sides.
-19x=149
Add 35 and 114 to get 149.
x=\frac{149}{-19}
Divide both sides by -19.
x=-\frac{149}{19}
Fraction \frac{149}{-19} can be rewritten as -\frac{149}{19} by extracting the negative sign.
