2 waffles =3$
2x4=8 waffles (How many waffles Sage wants)
3 + 3 + 3 + 3= 12 (or 3x4)
(2) (4) (6) (8)
<u>12$ at I Scream</u>
4 waffles= 4$
4 waffles x2=8$
<u>8$ at Scoopz</u>
12-8= 4
<h3>Sage would save 4 dollars if she got 8 waffles at Scoopz.</h3>

Explanation: 3*30=90 & 200-90=110 points
Substitute the first equation into the second equation. You will get:
4x - (2x - 5) = 7
Distribute the negative sign into the parenthesis:
4x - 2x + 5 = 7
Simplify
2x + 5 = 7
Subtract 5 on both sides
2x = 2
x = 1
Now, substitute x = 1 into the first equation:
y = 2(1) - 5
y = 2 - 5
y = -3
The solution to the system of equations is (1, -3).
Answer:
1. if x + 5 = 12, then x = 7
:Subtraction property of equality
2. If x + y = 20, and y = 5, then x + 5 = 20.
<u>:Substitution property of equality</u>
3. If 2x3 = 11, then 11 = 2x - 3.
<u>:Symmetric property of equality</u>
