    You can also graph the two equations. The point of intersection is the solution to the system https://www.desmos.com/calculator/xfkgtqxlj9

    olve the first equation for y: y = (6 - 2x) substitute in equation 2... - 4x + 3(6 - 2x) = 8 - 4x + 18 - 6x = 8 - 10x = - 10 x = 1 1,4 correct @imqwerty ?
