Hey there!
Answer:
x = 195
Step-by-step explanation:
So here is your equation:
90 = -105 + x
First, you simplify both sides of the equation:
90 = x - 105
Then, you will have to turn it around:
x - 105 = 90
So after you do that, you will have to Add the 105 to both sides:
x - 105 + 105 = 90 + 105
x = 195
So 195 is your answer.
Hope this helps! :D
