i am in algebra 1, i need help with this math problem badly~
You essentially have, on the right side, x + -1(-34) , which equals x + 34 right? (subtracting by a negative can be written as addition)
then subtract 34 from both sides and you are left with x = 90.
124=x-(-34) can also be written as 124=x+34 since subtracting a negative number is the same as adding a positive number.
we now want to isolate the x (get the x on the side by itself).
In order to do this, we will subtract 34 from both sides.
This gives us 124-34=x+34-34
The + and - 34 on the right side cancel out and all you are left with is x.
124-34 is 90 so the answer is 90=x OR x=90.
