Maryjo decided to solve the equation 3x-2=-x-6 by entering each of the expressions into her graphing calculator. to solve the equation as a system, she entered y1=3x-2 and y2=-x-6. when she used the calculator to find the intersection, she found x=-1 and y=-5. shoe the work to check to see if she found the correct solution for x to the linear equation.

Note that the problem states that you only need to check the solution she got for x...so we don't have to worry about y in this case. (YAY)

To verify MaryJo's answer, simply solve the equation for x:

3x - 2 = -x - 6
3x (+ x) - 2 = -x (+ x) - 6
4x - 2 = -6
4x - 2 (+ 2) = -6 (+ 2)
4x = -4
4x/4 = -4/4
x = -1

Since this confirms to MaryJo's answer, she did indeed find the correct solution for x.

Bis the answer! hope this

Hold on lemme do the work
