x-1=\frac{4}{7}
Consider the first equation. Divide both sides by 7.
x=\frac{4}{7}+1
Add 1 to both sides.
x=\frac{11}{7}
Add \frac{4}{7} and 1 to get \frac{11}{7}.
y=5\times \frac{11}{7}-1
Consider the second equation. Insert the known values of variables into the equation.
y=\frac{55}{7}-1
Multiply 5 and \frac{11}{7} to get \frac{55}{7}.
y=\frac{48}{7}
Subtract 1 from \frac{55}{7} to get \frac{48}{7}.
z=\frac{48}{7}
Consider the third equation. Insert the known values of variables into the equation.
x=\frac{11}{7} y=\frac{48}{7} z=\frac{48}{7}
The system is now solved.
