x=80-7
Consider the first equation. Subtract 7 from both sides.
x=73
Subtract 7 from 80 to get 73.
4\times 73+8y=750
Consider the second equation. Insert the known values of variables into the equation.
292+8y=750
Multiply 4 and 73 to get 292.
8y=750-292
Subtract 292 from both sides.
8y=458
Subtract 292 from 750 to get 458.
y=\frac{458}{8}
Divide both sides by 8.
y=\frac{229}{4}
Reduce the fraction \frac{458}{8} to lowest terms by extracting and canceling out 2.
x=73 y=\frac{229}{4}
The system is now solved.
