We are using substitution to solve this problem.
y=3x+1
y=-2x+3
Make these equal each other: 3x+1=-2x+3
Add 2x to both sides: 3x+2x+1=-2x+2x+3
= 5x+1=3
Subtract 1 from both sides; 5x+1-1=3-1
= 5x=2
Divide 5 from both sides: 5x/5=2/5
X= 2/5
Plug X into one of the equations: y=3(2/5) +1
y=11/5(2.2)
(2/5,11/5)
5 times n=17 because you have to use algebra
X - 0.17 = y
add 0.17 to both sides
x = y + 0.17
Do 1/2 x 1/10 which equals 10/2. 10/2 is 5 gallons if u divide 10 divided by 2. So the unit rate is 5 gallons per minute.
