Answer: 22 /5
-3+7y=5x+2y
Step-by-step explanation:
Subtract 2y from each side
-3+7y-2y=5x+2y-2y
-3 +5y = 5x
Add 5 to each side
5y = 5x+3
Divide each side by 5
y = 5x/5 +3/5
y = x +3/5
Let x = -5
y = -5 + 3/5
y = -25/5 +3/5
y = -22/5

The novel has 2160 pages.
Step-by-step explanation:
The number of pages of the novel is x.
Mica has read 1/2 of the novel, so x/2 = 0.5x.
Denise has read 2/5 of the novel, so 2x/5 = 0.4x.
Mica has read 216 pages more than Denise
This means that:
0.5x - 0.4x = 216
0.1x = 216
x = 216/0.1
x = 2160
The novel has 2160 pages.
