Answer:

h = 2 or h = -8/3

Step-by-step explanation:

Given equation,

|3h+1|=7h

3h + 1 = ± 7    (  ∵ |x| = y ⇒ x = ± y )

3h = ± 7 - 1

[tex]h=\frac{\pm 7-1}{3}[/tex]

[tex]h=\frac{7-1}{3}\text{ or } h=\frac{-7-1}{3}[/tex]

[tex]h=\frac{7-1}{3}\text{ or } h=\frac{-7-1}{3}[/tex]

[tex]\implies h = \frac{6}{3}=2\text{ or }h=-\frac{8}{3}[/tex]
