Solving Systems of Equations Using Substitution
Since both equations are equal to y, we can plug in 4x+3 as why in the second equation and solve for x4x+3=-x-2 5x+3=-2 (add x to both sides)5x=-5 (subtract 3 from both sides)x=-1 (divide both sides by 5)Then we can plug x=-1 into either orignial to solve for yy=-x-2y=-(-1)-2y=1-2y=-1So the answer is (-1,-1)Hope this helps
