Question

Pls help meee!!!!!!!!! Pls show your work pls and thank u

Answer 1

Answer: x = 40

Step-by-step explanation:

these two angles are vertical angles, they will equal each other

therefore, move numbers and variables to the opposite sides of the = sign to isolate the X

3x-10 = 2x + 30

   +10        +10           move the -10 by doing opposite

_____________

3x = 2x + 40

-2x   -2x                    move -2x by doing opposite

____________

x = 40

you can check your work by substituting 40 in place of x

3(40) - 10 = 2(40) +30

120-10 = 80 + 30

110 = 110

answer is correct

Answer 2

Answer:

x = 40

Step-by-step explanation:

The given angles are vertical angles, hence they are equal.

=============================================================

Solving for x :

⇒ 3x - 10 = 2x + 30

⇒ 3x - 2x = 30 + 10

⇒ x = 40
