y=2\times 14
Consider the fourth equation. Insert the known values of variables into the equation.
y=28
Multiply 2 and 14 to get 28.
28=a\times 14
Consider the third equation. Insert the known values of variables into the equation.
\frac{28}{14}=a
Divide both sides by 14.
2=a
Divide 28 by 14 to get 2.
a=2
Swap sides so that all variable terms are on the left hand side.
x=14 D=28 y=28 a=2
The system is now solved.
