How to solve 2x = 4? Get the answer and stepwise instruction to solve linear equation in one variable 𝒙.
We have 2x = 4
Divide both sides by 2, which is the coefficent of x
Note: if a = b, then a ÷ c = b ÷ c
2x2 = 42
x = 42
To simplify, divide both numerator and denominator by 2, which is the GCF of 4 and 2:
x = 21 or, x = 2
