6\left(-4+1\right)=2\left(-8-1\right)-3\left(-4+4\right)
Multiply both sides of the equation by 18, the least common multiple of 3,9,6.
6\left(-3\right)=2\left(-8-1\right)-3\left(-4+4\right)
Add -4 and 1 to get -3.
-18=2\left(-8-1\right)-3\left(-4+4\right)
Multiply 6 and -3 to get -18.
-18=2\left(-9\right)-3\left(-4+4\right)
Subtract 1 from -8 to get -9.
-18=-18-3\left(-4+4\right)
Multiply 2 and -9 to get -18.
-18=-18-3\times 0
Add -4 and 4 to get 0.
-18=-18+0
Multiply -3 and 0 to get 0.
-18=-18
Add -18 and 0 to get -18.
\text{true}
Compare -18 and -18.
