10=a\times 3^{2}+3
Subtract 1 from 4 to get 3.
10=a\times 9+3
Calculate 3 to the power of 2 and get 9.
a\times 9+3=10
Swap sides so that all variable terms are on the left hand side.
a\times 9=10-3
Subtract 3 from both sides.
a\times 9=7
Subtract 3 from 10 to get 7.
a=\frac{7}{9}
Divide both sides by 9.
