WILL MARK BRAINEST PLZ HELP! What is the value of x? (With all of the details on how to get it.
klasskru [66]

To find x:

Subtract 10 on both sides.

10 + 2x = 90

-10           -10

Divide 2 on both sides.

2x = 80

---     ---

2        2

This would get x alone.

x = 40

Check:

10 + 2(40) = 90

10 + 80 = 90

90 = 90

The value of x is 40. The angle degree of it is 80 when you multiply 2 by 40.
