WebTake the 2nd equation and add 3x to both sides to isolate "y". y = 3x+3 Now, substitute this value of "y" into the first equation. 3(3x+6) + 2x = 7 You can now solve for "x". Once you have the value of "x", use it to calculate the value of "y". Hope this helps. Comment back if you have questions.
