Question

|4x - 2| = 10

x = 3 & x = -3

x = 3 & x = 2

x = 3 & x = -2

x = 2 and x = -2

Answer 1

Answer:

x = 3 & x =- 2

Step-by-step explanation:

|4x - 2| = 10

separate this into 2 equations a positive and a negative

4x-2 =10    and 4x-2 = -10

add 2 to each side

4x-2+2 =10+2     4x-2 +2 = -10 +2

4x =12                4x = -8

divide by 4

4x/4 = 12/4         4x/4 = -8/4

x =3                 x=-2
