Shania Branch · Answer 1

We are already given the equation to solve:

x + 3x + 5 = 21

The constant can be transposed to the other side

x + 3x = 21 - 5

The variables can be combined

4x = 21 - 5

The constants combine,

4x = 16

Dividing the whole equation with 4

4x/4 = 16/4

Cancelling out terms

x = 4

Therefore, the answer is

A. 4 bicycles
