Step-by-step explanation:

Oklahoma became a state in year x.

Arizona became a state in 1912. This was 5 years after Oklahoma became a state.

This means that:

1912 = x + 5

The equation that can be used to find the year Oklahoma became a state is 1912 = x + 5

Solving the equation for x:

x = 1912 - 5 = 1907

So, Oklahoma became a state in 1907
