Angle A is 12x - 37 and angle B is 7x + 15. If these angles are vertical, what is the value of x? x=?

CAN ANYONE HELP ME PLEAS//

x = -439

Step-by-step explanation:

Oh, ok this one will take a while for me to type ;) breath in and breath out!

Ok so watch my steps:

1. 12 - 37

multiply #1 by 7

1. 84x - 259

now multiply #2 by 12 and line 'em up

2. 84 + 180

1.  84x - 259 ( -

-----------------------

        x + 439 = 0

             x       = 0 -439

                   x = -439

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x - 4y = - 2 → (1)

3x + y = 4 → (2)

Multiplying (2) by 4 and adding the result to (1) will eliminate the y- term

12x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

14x + 0 = 14

14x = 14 ( divide both sides by 14 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

3(1) + y = 4

3 + y = 4 ( subtract 3 from both sides )

y = 1

solution is (1, 1 )
