Answer:
The answer to your question is: x = 7; y = 6
Step-by-step explanation:
2x+y=20 ( 1 ) Multiply by 5
6x−5y=12 ( 2 )
5 (2x+y=20) = 10x + 5y = 100
10x + 5y = 100
6x − 5y = 12 Eliminate y
16 x = 112
x = 112 / 16
x = 7
2(7) + y = 20 Substitution
14 + y = 20
y = 20 - 14
y = 6
1 feet = 12 inches
1 min = 60 s
1 feet/min = 12 in/60 s = 1 in/5 s = 0.2 in/s
Answer:
33
Step-by-step explanation:
- Fabric for 1 pillow case: 1.5 ÷ 3 = 0.5
- Amount of pillow cases made with 16.5 yards of fabric: 16.5 ÷ 0.5 = 33

Answer:
(1, 3 )
Step-by-step explanation:
To find a solution to the equation.
Rearrange making y the subject by subtracting 6x from both sides
Given
6x + y = 9, then
y = 9 - 6x
Substitute any value of x into the equation and solve for y to obtain a solution
x = 1 → y = 9 - 6(1) = 9 - 6 = 3
Thus (1, 3) is a solution to the equation
