Answer:
x = -1
Step-by-step explanation:
- 10 + x + 4 - 5 = 7x - 5
-11 + x = 7x - 5
-6 + x = 7x
-6 = 6x
x = -1
Since its telling you that x is the number of years and the question is "How much does the cost of milk increase EVERY YEAR" then you can conclude that the cost is increasing by 0.25 each year
Answer:
1.Solve for y in 2x+y=-3
y=-3-2x
2. Substitute y= -3 - 2x into 4x-2y=10
8x+6=10
3 Solve for x in 8x+6=10
x=1/2
4. Substitute x=1/2 into y = - 3 - 2x
y= -4
5. So you get...,
x=1/2
y=−4
