Answer:
x = 25
Step-by-step explanation:
[tex]\frac{x}{2}[/tex] - 5 = 10
Our goal is to get x by itself. We can see that it is currently being divided by 2. So, we can multiply it by 2 to get it by itself. Remember that what you do to one side of an equation you must do to the other.
2 · [tex]\frac{x}{2}[/tex] - 5 = 10 · 2
The 2s on the left side of the equation cancel each other out, leaving us with x.
x - 5 = 10 · 2
Multiply 10 and 2.
x - 5 = 20
We still need to get x by itself. To do this, we can move the -5 to the right side. Remember: "change the side, change the sign." The -5 will become +5 when moved to the other side.
x = 20 + 5
Add 20 and 5.
x = 25
