10=2x^{1}+x^{1}
Calculate 10 to the power of 1 and get 10.
10=2x+x^{1}
Calculate x to the power of 1 and get x.
10=2x+x
Calculate x to the power of 1 and get x.
10=3x
Combine 2x and x to get 3x.
3x=10
Swap sides so that all variable terms are on the left hand side.
x=\frac{10}{3}
Divide both sides by 3.
