Just remember BODMAS, which B= brackets O= Order D= Division M= Multiply A=Addition and S=Subtract
So first you solve the brackets so 44+22 is 66
So 66-4+12 so 66-4 is 62
62+12 is 74
So now you have got 74 divided by 2 which is 37
Hope this helps xx
Most of the time its juss common sense where you can point the right measurement with just sense i guess
The final answer is:
y - 34 = x2 - 12x
