Question

Which of the following is the value of x such that

5x – 12 = - 2
(a) 2
(b) - 2
(c) 23
(d) 10

Answer 1

A) 2

Explanation:

5x - 12 = -2 Add 12 to both sides

5x - 12 + 12 = -2 + 12

5x = 10 Divide both sides by 5

`(5x)/(5)` =
`(10)/(5)`

x = 2

Answer 2

`\sf \: (a) \: 2`

Explanation:

Given equation,

→ 5x - 12 = -2

Now the value of x will be,

→ 5x - 12 = -2

→ 5x = -2 + 12

→ 5x = 10

→ x = 10/5

→ [ x = 2 ]

Hence, the value of x is 2.
