Step-by-step explanation:
Answer:
x = 3
y = 2
Step-by-step explanation:
Given
y = -2x + 8
y = x - 1
Substitute x - 1 for y in the first equation
We have
y = -2x + 8
x - 1 = -2x + 8
Add 1 to both sides to eliminate 1 on the left side
x - 1 + 1 = -2x + 8 + 1
x = -2x + 9
Add 2x to both sides to eliminate 2x on the right side
x + 2x = -2x + 2x + 9
3x = 9
Divide both sides by 3 to isolate x
3x/3 = 9/3
x = 3
Now substitute 3 for x in either equations to get y
Using the second equation, we have
y = x - 1
y = 3 - 1
y = 2
x = 3 and
y = 2
Answer: x = 5
Step-by-step explanation:
14 / 2 = 7
7 * 5 = 35
Same applies for x
2 / 2 = 1
1 * 5 = 5
Answer:
The unit rate is $9.20 per toy
Step-by-step explanation:
Since the total of the toys is 46, you divide by 5, to see how much each toy is
