Answer 1

`\sf \: x = - 4`

Explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 3x + 5 = -7

Then the value of x will be,

→ 3x + 5 = -7

→ 3x = -7 - 5

→ 3x = -(7 + 5)

→ 3x = -12

→ x = -12 ÷ 3

→ [ x = -4 ]

Hence, the value of x is -4.

3x = -12

divide both sides by 3

x = -4
