    You can solve it by graphing or doing algebra.

    Well I you graph the equation just look at the point where the line crosses the x-axis.

    it crosses the x-axis at some value of x. That "some value of x" is the solution of the equation.

    ok cool now the last one I need help with is . Create a linear equation in two variables in the form Ax + By = C to graph using the x- and y- intercept method.

    You need to do the same, plug values into the A, B, and C. Can you do that?

    so like this 2a+4b=c ?right

    Not exactly, but you are close. I meant plug values into the A, B, C, for example: \[2x+4y=4\]
