Answer:
The equation that can be used to find the year Oklahoma became a state is 1912 = x + 5
Oklahoma became a state in 1907
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
