\left(8x+300-6x\right)\times 0\times 8\leq 213
Use the distributive property to multiply 50-x by 6.
\left(2x+300\right)\times 0\times 8\leq 213
Combine 8x and -6x to get 2x.
\left(2x+300\right)\times 0\leq 213
Multiply 0 and 8 to get 0.
0\leq 213
Anything times zero gives zero.
\text{true}
Compare 0 and 213.
