n=4\times 20
Consider the first equation. Multiply both sides by 20.
n=80
Multiply 4 and 20 to get 80.
x=11\times 7
Consider the second equation. Multiply both sides by 7.
x=77
Multiply 11 and 7 to get 77.
b=\frac{64}{16}
Consider the third equation. Divide both sides by 16.
b=4
Divide 64 by 16 to get 4.
n=80 x=77 b=4
The system is now solved.
