-3x-1 = 2-(-3)
-3x-1 = 2+3
-3x-1 = 5
-3x = 5+1
-3x = 6
x = 6/(-3)
x = -2
Answer:
(-1,1)
Step-by-step explanation:
x + 9y = 8
-6x - 9y = -3
Add the two equations together to eliminate y
x + 9y = 8
-6x - 9y = -3
---------------------
-5x = 5
Divide by -5
-5x/-5 = 5/-5
x = -1
Now solve for y by substituting into the first equation
x+9y = 8
-1 + 9y =8
Add 1 to each side
-1+1 + 9y = 8+1
9y=9
Divide each side by 9
9y/9 = 9/9
y = 1
Yep they do, because if you plug in y for both equations, you get x=0. To find y, plug in 0 for either equation to get -7. (0,-7) should work for both equations since the intersection point is the point where both equations meet.
