\frac{x+2\times 7}{4}=\frac{25}{9}
Consider the first equation. Divide both sides by 9.
x+2\times 7=\frac{25}{9}\times 4
Multiply both sides by 4.
x+14=\frac{25}{9}\times 4
Multiply 2 and 7 to get 14.
x+14=\frac{100}{9}
Multiply \frac{25}{9} and 4 to get \frac{100}{9}.
x=\frac{100}{9}-14
Subtract 14 from both sides.
x=-\frac{26}{9}
Subtract 14 from \frac{100}{9} to get -\frac{26}{9}.
x=-\frac{26}{9} y=3 z=3
The system is now solved.
