Solving Systems of Linear Equations by graphing. 3y+4x=3 and x+3y=-6. Can someone help me with where the lines intersect and show me how they solved it on paper? I keep getting it wrong even though i think its right but i just need a second opinion
The best way to do this question is to use elimination. Elimination is a way to find out the POINT OF INTERSECTION between two lines. Let me show you how.
3y+4x=3 x+3y=-6
Elimination is a way to remove any same variable with the same coefficient. In this case, there is 3y in both equations. In this case, we subtract to eliminate.
3y-3y+4x-x=3+6 It's plus 6 because two negatives become positive. 3x=9 Divide both sides by 3 x=3
Now you can find y.
x+3y=-6 3+3y=-6 3y=-9 y=-3
Therefore, the POI is (3,-3). I hope you understand this. Make sure to mark as brainliest.
