First make the equation:
1. x
2. 3x
x + 3x = 48
Now solve it:
x + 3x = 48
4x= 48
x=12
Now plug in x
1. x = 12
2. 3x = 36
So Kayla sold 12 blue t-shirts and 36 white t-shirts.
Set each equation equal to zero.
y + 5 = 0
Subtract 5 from both sides.
y = 0 - 5
y = - 5
y - 9 = 0
Add 9 to both sides
y = 0 + 9
y = 9
y = - 5, 9
Answer:
10
Step-by-step explanation:
Let the no. of sodas be x
Price of each soda = $2
Therefore, no . of sodas you can buy = $2x
2x=20
=>x=
=>x=10
you can buy 10 sodas
