\left(1+0\right)x\times 0\times 9-x=20
Multiply 0 and 2 to get 0.
1x\times 0\times 9-x=20
Add 1 and 0 to get 1.
0x\times 9-x=20
Multiply 1 and 0 to get 0.
0x-x=20
Multiply 0 and 9 to get 0.
0-x=20
Anything times zero gives zero.
-x=20
Anything plus zero gives itself.
x=-20
Multiply both sides by -1.
