That would be written as:

And the step-by-step equation would be:
→ we take the 2 to the right side of the equation and do the IO*
→we solve for 
→ final answer
*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)

-3-(-3)(-1)= 0, so 0 is the solution
Answer+Step-by-step explanation:

Alternate Interior Angles. You’re welcome
Its basically just subtracting from one another
for example, 6-6 is 6
or -4-3= 7
