Question

Solve the equation. 3 + |t + 4| = 10

Question 9 options:

[-3, 11]


[-11, 3]


[3, 11]


[-3, -11]

Answer 1

b) [-11, 3]

Explanation:

Given equation,

→ 3 + |t + 4| = 10

Now the value of t will be,

→ 3 + |t + 4| = 10

→ 3 + t + 4 = 10 || → 3 -(t + 4) = 10

→ t + 7 = 10 || → -t - 1 = 10

→ t = 10 - 7 || → -t = 10 + 1

→ [ t = 3 ] || → [ t = -11 ]

Hence, value of t is 3 (or) -11.
