# How can x + 4 = 3x + 12 be set up as a system of equations?

**Solution:**

System of equations is a collection or set of equations which are dealt together.

These equations can be solved algebraically and graphically.

The point where these two lines intersect is the solution to the system of equations.

Given: x + 4 = 3x + 12

It has to be set up as a system of equations

The given equation contains two sides

x + 4 on the LHS and 3x + 12 on the RHS

In order to set up a system of equation let us equate the LHS and RHS to a variable y

So it becomes,

y = x + 4

y = 3x + 12

Therefore, x + 4 = 3x + 12 can be set up as a system of equations as y = x + 4 and y = 3x + 12.

## How can x + 4 = 3x + 12 be set up as a system of equations?

**Summary:**

x + 4 = 3x + 12 can be set up as a system of equations as y = x + 4 and y = 3x + 12.
