Question

Solve

|4t-8|=20

a
t=-3

b
t=-7

c
t=3

d
t=7

Answer 1

a) t = -3

d) t = 7

Explanation:

Given equation,

→ |4t - 8| = 20

Solving for the value of t,

→ |4t - 8| = 20

→ 4t - 8 = 20 || -4t + 8 = 20

→ 4t = 20 + 8 || -4t = 20 - 8

→ t = 28/4 || t = -(12/4)

→ [ t = 7 ] || [ t = -3 ]

Hence, value is 7 and -3.
