f-91=14
Consider the first equation. Multiply both sides of the equation by 7.
f=14+91
Add 91 to both sides.
f=105
Add 14 and 91 to get 105.
r=121-84
Consider the second equation. Subtract 84 from both sides.
r=37
Subtract 84 from 121 to get 37.
18\times 12=w
Consider the third equation. Multiply both sides by 12.
216=w
Multiply 18 and 12 to get 216.
w=216
Swap sides so that all variable terms are on the left hand side.
14p+23=79
Consider the fourth equation. Swap sides so that all variable terms are on the left hand side.
14p=79-23
Subtract 23 from both sides.
14p=56
Subtract 23 from 79 to get 56.
p=\frac{56}{14}
Divide both sides by 14.
p=4
Divide 56 by 14 to get 4.
f=105 r=37 w=216 p=4
The system is now solved.
