The solution to the equation is x = 4

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the solution to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the equation is given as

(x + 20)/2 = 3x

Multiply both sides of the equation by 2

x + 20 = 6x

Subtract x from both sides of the equation

5x = 20

Divide both sides of the equation by 5

x = 4

hence, the solution to the equation is x = 4
