Solve for a
a = \frac{100}{17} = 5\frac{15}{17} \approx 5.882352941
Solve for b
b\in \mathrm{R}
a = \frac{100}{17} = 5\frac{15}{17} = 5.882352941176471

a+b-a-b+8a+9a=100
To find the opposite of a+b, find the opposite of each term.
b-b+8a+9a=100
Combine a and -a to get 0.
8a+9a=100
Combine b and -b to get 0.
17a=100
Combine 8a and 9a to get 17a.
a=\frac{100}{17}
Divide both sides by 17.
