Since both equations equal Y, set them equal to each other and solve.
3x -1 = -2x +9
Add 2x to each side:
5x - 1 = 9
Add 1 to each side:
5x = 10
Divide both sides by 5:
x = 10/5
x = 2
Now replace x with 2 and solve for y:
y = 3(2) -1 = 6-1 = 5
x = 2, y = 5 (2,5)
First to find what’s 2x you do 25-11=14, and you know that 7 x 2 =14.
So x= 7.
-2(5)^2+2(5)-3
-2(25)+10-3
-50+10-3
-40-3
=-43
