Question

9x + 15 = 20 - x please helppp

Answer 1

x = 1/2

Explanation:

To solve this, we want x on just 1 side.

We can add x to both sides, to get 10x+15=20 (so we have moved the x across).

Lets now move the numbers onto just one side (we can do this by -15 from both sides).

Consequently, 10x=5

To find x on its own, we can do 5/10, therefore x=1/2

Answer 2

Answer: 1/2

Explanation:

9x+15=20-x

=> 9x+x=20-15

=>10x=5

=>x=5/10

= x=1/2
