7 ∣x−2∣+7=−2∣x−2∣ +2

 x=2.

Step-by-step explanation:  a. \displaystyle |6x+4|=8∣6x+4∣=8

Write two equations and solve each:

The two solutions are \displaystyle x=\frac{2}{3}x=

, \displaystyle x=-2x=−2.

b. \displaystyle |3x+4|=-9∣3x+4∣=−9

There is no solution as an absolute value cannot be negative.

c. \displaystyle |3x - 5|-4=6∣3x−5∣−4=6

Isolate the absolute value expression and then write two equations.

d. \displaystyle |-5x+10|=0∣−5x+10∣=0

The equation is set equal to zero, so we have to write only one equation.
