Solve for a, b
a = \frac{5}{2} = 2\frac{1}{2} = 2.5
b = \frac{9}{2} = 4\frac{1}{2} = 4.5

a=\frac{5}{2}
Consider the first equation. Divide both sides by 2.
\frac{5}{2}+b=7
Consider the second equation. Insert the known values of variables into the equation.
b=7-\frac{5}{2}
Subtract \frac{5}{2} from both sides.
b=\frac{9}{2}
Subtract \frac{5}{2} from 7 to get \frac{9}{2}.
a=\frac{5}{2} b=\frac{9}{2}
The system is now solved.
