Answer:
LEFT
k + 3 = 20,
k = 17
RIGHT
3x + 5 = 32,
k = 9
Step-by-step explanation:
For the left side, you have k + 3 on one side equaling 20, so the equation is
k + 3 = 20
To solve is as follows
k + 3 = 20
- 3 - 3
k = 17
For the right side,
You have 3 x's and 5 1's right? Adding them together will equal 32 (Other side
So your equation is 3x + 5 = 32
To solve is as follows
3x + 5 = 32
- 5 -5
3x = 27
Dividing both sides by 9 we get x = 9
Reasoning; you want to cancel out everything with x so that you got x alone on one side.
Hope this helps, if not comment on this telling me which step I did that you dont understand and I'll explain it.

Answer:
y=-4x-25
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-3)/(-6-(-7))
m=-4/(-6+7)
m=-4/1
m=-4
y-y1=m(x-x1)
y-3=-4(x-(-7))
y-3=-4(x+7)
y=-4x-28+3
y=-4x-25
y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
