Question

….. solve for X………….

Answer 1

x=5

Explanation:

these two angles are the same so set both equations equal to each other and solve for x.

`23x-5=21x+5\\23x=21x+10\\2x=10\\x=5`

1. set equations equal to each other

2. add 5 to both sides

3. subtract 21x from both sides

4. divide both sides by 2 to get x alone

5. x=5
