How to solve 3x = 12? Get the answer and stepwise instruction to solve linear equation in one one variable 𝒙.

We have 3**x** = 12

Divide both sides by 3, which is the coefficent of **x**

**Note: ** if a = b, then a ÷ c = b ÷ c

3**x**3 = 123

**x** = 123

To simplify, divide both numerator and denominator by 3, which is the GCF of 12 and 3:

**x** = 41 or, **x** = 4
