Answer:
y = 3x - 2
Step-by-step explanation:
y +8 = 3 (x + 2)
y + 8 = 3x + 6
y = 3x - 2
This question is worded slightly strangely but I believe I understand it.
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
Then you can subtract 4x on the top by 4x on the bottom to eliminate it.
Answer:
4
Step-by-step explanation:
(8)+2=4
16=4
16=4•4
16=16
The answer is $85.50
57 x 50% or 57 x .5 = 28.50
Add $28.50 to $57 and you get $85.50
