9\left(1\times 2+1\right)s=3\left(-5\right)^{2}+6\times \left(\frac{3}{3}\right)^{2}
Multiply both sides of the equation by 18, the least common multiple of 2,18,3.
9\left(2+1\right)s=3\left(-5\right)^{2}+6\times \left(\frac{3}{3}\right)^{2}
Multiply 1 and 2 to get 2.
9\times 3s=3\left(-5\right)^{2}+6\times \left(\frac{3}{3}\right)^{2}
Add 2 and 1 to get 3.
27s=3\left(-5\right)^{2}+6\times \left(\frac{3}{3}\right)^{2}
Multiply 9 and 3 to get 27.
27s=3\times 25+6\times \left(\frac{3}{3}\right)^{2}
Calculate -5 to the power of 2 and get 25.
27s=75+6\times \left(\frac{3}{3}\right)^{2}
Multiply 3 and 25 to get 75.
27s=75+6\times 1^{2}
Divide 3 by 3 to get 1.
27s=75+6\times 1
Calculate 1 to the power of 2 and get 1.
27s=75+6
Multiply 6 and 1 to get 6.
27s=81
Add 75 and 6 to get 81.
s=\frac{81}{27}
Divide both sides by 27.
s=3
Divide 81 by 27 to get 3.
