Answer:
x=2 and y=1
Step-by-step explanation:
Add the two equations to remove "y" and solve for x:
4x+8y=16
6x-8y=4
________
10x=20
x=2
Plug x=2 into one of the original equations to get the value of "y":
4x+8y=16
4(2)+8y=16
8+8y=16
8y=8
y=1
Therefore, x=2 and y=1
Answer:
2(7) + 5 = 19
Step-by-step explanation:
Okay, so do it like this:
2x+5
x = 7
2(7) + 5
2(7) = 2 x 7
2 x 7 = 14
Now it's 14 + 5
14 + 5 = 19
Your answer is 2(7) + 5 = 19
Answer:
M has 41 CDs
Step-by-step explanation:
Joel = 2 x M
(Joel -7) / 3 = Black
Black = 25
Joel - 7 = 3 x Black = 3 X 25 = 75
Joel = 75 + 7 = 82
M = 82 / 2 = 41
