Answer:
x = 20
Step-by-step explanation:
The goal is to move the x's and the whole numbers to their own sides of the equation. When moving pieces to opposite sides, the signs change (a negative becomes a positive, for example).
3x - 4 = 2(x + 8)
First we're going to use distributive property to remove the brackets in
2(x + 8)
This becomes 2x + 16
3x - 4 = 2x + 16
Moving 2x over...
3x - 2x - 4 = 16
Moving -4 over...
3x - 2x = 16 + 4
Collecting like terms...
x = 20
Answer:
11
Step-by-step explanation:
So when we scale up this image, all points' distances from the center are multiplied by
. We want to then put them back to where they were before.
Thinking about inverse operations, we could just divide by
as
, then the opposite reciprocal would be
