WebI'll get you started. Take 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. WebSometimes we can apply a function to both sides (e.g. square both sides) Example: Solve √ (x/2) = 3 Start with: √ (x/2) = 3 Square both sides: x/2= 32 Calculate 3 2 = 9: x/2 = 9 Multiply both sides by 2: x = 18 And the more "tricks" and techniques you learn the better you will get.
