88=4\times 9\times 2+2\times 2H
Consider the first equation. Insert the known values of variables into the equation.
88=36\times 2+4H
Do the multiplications.
88=72+4H
Multiply 36 and 2 to get 72.
72+4H=88
Swap sides so that all variable terms are on the left hand side.
4H=88-72
Subtract 72 from both sides.
4H=16
Subtract 72 from 88 to get 16.
H=\frac{16}{4}
Divide both sides by 4.
H=4
Divide 16 by 4 to get 4.
S=88 L=9 W=2 H=4
The system is now solved.
