How do you solve this ??

Hi there!

If the lines are parallel, Angles 1 and 2 would have to be congruent because they are corresponding angles. Therefore, to solve, all we need to do is set the values of the angles equal to each other because the angles are congruent.

WORK:
20 - 8x = 30 - 16x
-8x = 10 - 16x
8x = 10
x = 1.25

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

6(x-2)=5x+3x+8 solve for x.
Mnenie [13.5K]

Answer:

x = -10

Step-by-step explanation:

 6 • (x - 2) -  (8x + 8)  = 0

Pulling out like terms :

3.1     Pull out like factors :

  -2x - 20  =   -2 • (x + 10)

Equation at the end of step  3  :

 -2 • (x + 10)  = 0

Equations which are never true :

4.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    x+10 = 0

Subtract  10  from both sides of the equation :

                     x = -10

One solution was found :

                  x = -10

plz mark me as brainliest :)
