5\times 21+x\times 5=5.5\times 26
Multiply both sides by 26.
105+x\times 5=5.5\times 26
Multiply 5 and 21 to get 105.
105+x\times 5=143
Multiply 5.5 and 26 to get 143.
x\times 5=143-105
Subtract 105 from both sides.
x\times 5=38
Subtract 105 from 143 to get 38.
x=\frac{38}{5}
Divide both sides by 5.
