Hey Kayla!
Let me help you out real quick.
x - 2y = 5
-3x + 2y = 7
We need to solve x - 2y =5 for x
x - 2y = 5
x = 5 + 2y
Now substitute 2y + 5 for x in -3x + 2y = 7
-3x + 2y = 7
-3(2y + 5) + 2y = 7
-6y - 15 + 2y = 7
-4y - 15 = 7
-4y = 7 + 15
-4y = 22
y = 22/-4
y = -11/2
Now we need to substitute -11/2 for y in x= 2y + 5
x = 2y + 5
x = 2(-11/2) + 5
x = -22/2 + 5
x = -6
Thus,
The answer is x = -6 and y = -11/2
The correct answer is option D
Good luck with your studies :)
You got it!

Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25
Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450
Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420
The class earned more money in September and they earned $30 more than in October.

Answer: y = (1/4)x + 3/4</h3>
m = 1/4 = slope
b = 3/4 = y intercept
===================================================
Explanation:
The goal is to solve for y.
Divide both sides by 4 and simplify like so
4y = x+3
4y/4 = (x+3)/4
y = (x+3)/4
y = x/4 + 3/4
y = (1/4)x + 3/4
This equation is in slope intercept form y = mx+b
m = 1/4 is the slope
b = 3/4 is the y intercept
The graph is a straight line that goes through (1,1) and (5,2)
