Question

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

Answer 1

x + 4 = 3x + 12

y = x + 4
y = 3x + 12

Answer 2

The system becomes,

y = x + 4

and y = 3x +12

Explanation:

Given: x + 4 = 3x + 12

We have to set up the given equation as a system of equations.

Given equation x + 4 = 3x + 12 has two sides

left side x + 4 and right side 3x + 12

To set up a system of equation put the given Left side and right side equal to some equal variable say y.

Thus, the system becomes,

y = x + 4

and y = 3x +12
