Answer:
x=3
Step-by-step explanation:
3x+1=10
3x-1=-1
3x=9
÷3=÷3
x=3
We hates fractions
times everybody by 6x
6=x²-5x
minus 6 both sides
0=x²-5x-6
factor
what 2 numbers multiply toget -6 and add to get -5
-6 and 1
0=(x-6)(x+1)
set to zero
x-6=0
x=6
x+1=0
x=-1
x=6 or -1
Answer: y= 16 - 3/2x
Step-by-step explanation:
3x+2y=32 (subtract 3x from both sides)
2y=32-3x (divide both sides by 2)
y= 16 - 3/2 x
If solving for x:
3x + 2y = 32
3x = 32- 2y
x = 32/3 - 2/3 y

Answer: $50 + $2.49x = $67.43
Step-by-step explanation:
Let the case of water bought be represented by x.
We are informed that Sam's Club has a special that charges $2.49 per case of water and that Vinny wants to pay that price, but needs to purchase a membership first, which costs $50 and that Vinny eventually spent $67.43.
The equation that represents the number of cases of water that Vinny bought at Sam's club will be:
$50 + $2.49x = $67.43
