My question is how would u do a problem like this..........
I am not sure what your question is.
If the square brackets on the left side of the equation are just brackets then I assume that you are to solve [2x-37] =15. In that case my solution would be:
Add 37 to both sides to get 2x - 37 + 37 = 15 + 37
That is 2x = 52.
Now divide both sides by 2 to get x = 26.
If the brackets on the left side designate absolute value,
In the case that 2x - 37 = 15 then we solved this equation above and got x = 26.
In the case that 2x - 37 = -15 then arguing as above gives x = 11.
Thus either x = 26 or x = 11.
