Solve 3/3 = 20/x

How to solve 3/3 = 20/x? Get the answer and stepwise instruction to solve linear equation in one variable 𝒙.

We have 3/3 = 20/x

Cross multiplying the ratios, gives

3x = 3 × 20

Divide both sides by 3, which is the coefficient of x
Note: if a = b, then a ÷ c = b ÷ c

Therefore, 3x/3 = 3 × 20/3

x = 60/3

To simplify, divide both numerator and denominator by 3, which is the GCF of 60 and 3:

x = 20/1 or, x = 20
