Answer:

Step-by-step explanation:
The given equations are:
1st: -3x=42-16y
2nd: 14x=76-16y
Subtract the first equation from the second one:
14x--3x=76-42-16y--16y
14x+3x=34-16y+16y
17x=34

We plug in x-value into the second equation to get:
14(2)=76-16y
14x=76-32
28-76=-16y
-48=-16y
Divide both sides by -16
y=3
Answer:
i think it may be 21.98 but i dunno
Step-by-step explanation:
Answer:
- y = -3/5 × -5 - 2
- y = 2 × -1 + 2
Step-by-step explanation:
#1
- y = mx + b
- m = -3/5, x = -5, b = -2, y = y
- put in correct order
#2
- (2, -1) - (5,5) = 6/3 = 2/1 = 2 (remember, y is over x. The formula is y2 - y1 / x2 - x1)
- Pick either point given (2, -1) or (5, 5)
- Plug the point in
- y = y, m = 2, x = 2, b = -1
- Put in order
