Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation 
-----> equation 
Substitute equation
in equation 
![[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7](https://tex.z-dn.net/?f=%20%5B3y%5D%2By%3D28%5C%5C%204y%3D28%5C%5C%20y%3D28%2F4%5C%5C%20y%3D7%20)
find the value of x

therefore
the answer is
Sari has
erasers
Answer:
(-4,-7)
Step-by-step explanation:
Answer: (10x + 30)
Step-by-step explanation:
1. combine like terms. -4x + 3x = -x
2. you can’t have a negative x, so you would multiply the equation (-x+3) by -1, to get (x-3).
3. (x-3)(10)... 10 • x = 10x, 10 • 3 = 30.
4. put them together, answer would be 10x + 30.
He will spend at least $27. He has already spent $16
27-16=11
So, Henry will spend at least 11 more dollars
C ≥ 11
