Answer:
145
Step-by-step explanation:
We will let x equal our unknown number. So:
(x + 5)/2 = 75
Now we can solve for x
We can first multiply both sides of the equation by 2. This will get rid of the fraction on the left side:
x + 5 = 75 * 2 ----->
x + 5 = 150
Next, subtract 5 from both sides:
x + 5 - 5 = 150 - 5 ----->
x = 145
