3\left(8-1\right)+2\left(1+2\right)=12
Multiply both sides of the equation by 6, the least common multiple of 2,3.
3\times 7+2\left(1+2\right)=12
Subtract 1 from 8 to get 7.
21+2\left(1+2\right)=12
Multiply 3 and 7 to get 21.
21+2\times 3=12
Add 1 and 2 to get 3.
21+6=12
Multiply 2 and 3 to get 6.
27=12
Add 21 and 6 to get 27.
\text{false}
Compare 27 and 12.
