Answer: Infinite solutions

Explanation:

We are given a system of equations of two linear equations. To solve for x and y, we can use the elimination method.

Given:

6x + 3y = 54

2x + y = 18​

Opposite coefficients:

6x + 3y = 54

-3 * (2x + y = 18​)

-

6x + 3y = 54

-6x - 3y = -54

Add the equations together:

0 + 0 = 0

Since both of the variables cancel out, but 0 does equal 0, there are infinite solutions to this system of equations.

We can also graph the given equations. Both of these equations are the same (when simplified into slope-intercept form) so they directly overlap each other. These equations can both become y = -2x + 18.

6x+3y = 54 2x+y = 18​-example-1
