x - 3y = 1 ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
-14y = -8
-14 -14
y = ⁴/₇
x - 3y = 1
⁴/₇ - 3y = 1
- ⁴/₇ - ⁴/₇
-3y = ³/₇
-3 -3
y = ⁻¹/₇
(x, y) = (⁴/₇, ⁻¹/₇)

Answer:
<u>There are 60 toddlers in the preschool class</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Percentage of the toddlers in a preschool class drink water with their lunch = 5
Number of the toddlers in a preschool class drink water with their lunch = 3
2. How many toddlers are in the class?
We'll solve the question, using the Direct Rule of Three, this way:
Percentage Toddlers
5 3
100 x
*******************************
5x = 3 *100
5x = 300
x = 300/5
x = 60
<u>There are 60 toddlers in the preschool class</u>
Answer:
100
Step-by-step explanation:
200+3qq+400+q3q
200+3q²+400+3q²
3q²-3q²+400-200
q²=200
q²=200/2
q²=100
