So the easiest method that can be used would be substitution. This is what you do... Plug in the y-value into the second equation. -4x + 3(x - 4) = -3 Distribute. -4x + 3x - 12 = -3 Combine like-terms. -1x - 12 = -3 Add 12 to both sides to isolate the variable. -1x = 9 Divide. x = -9 Now we need to find the y-value. Plug in x with -9 in the first equation. y = x - 4 y = -9 - 4 y = -13 So your solution is (-9, -13) I hope this helps love! :)
