x=\frac{15}{5}
Consider the first equation. Divide both sides by 5.
x=3
Divide 15 by 5 to get 3.
y=3\times 3+2\times 3
Consider the second equation. Insert the known values of variables into the equation.
y=9+6
Do the multiplications.
y=15
Add 9 and 6 to get 15.
a=15
Consider the fourth equation. Insert the known values of variables into the equation.
x=3 y=15 z=15 a=15 b=15
The system is now solved.
