1) the solution x = 1/2 is a solution to which of the following equations? 5x = 20 4 = 15x -4x = 60 30 = 60x 2) solve the following equation: |5x| = 20 -20, 20 -4, 4 4, 20 -4, 20

You will try all the cases and see if all the equations will match after substituting or no.
1.
5x
put x = 1/2
2.5 isn't equal to 20

4=15x
put x =1/2
15 × 1/3 =7.5
7.5 isn't equal to 4

-4x = 60
put x = 1/2
-4×1/2 = -2
-2 isn't equal to 60

30 = 60x
pit x = 1/2
60 × 1/2 = 30
30 = 30

Therefore, the correct answer is D. 30 = 60x

2. Answer is B. -4 , 4

Put x = -4
l 5 × -4 l = l-20l = 20
20 = 20

Put x = 4
l 5 × 4 l = l20l = 20
20 = 20

It’s d for sure i just did also that’s why
