Y is the same sorry if i’m incorrect
Answer:
X = 2
Step-by-step explanation:
The amount of decrease is (80 - 64) = 16
The fraction of decrease is the fraction of the original amount that disappeared.
That fraction is (16 / 80) = 1/5 = 0.2
To change a decimal to a percent,
move the decimal point 2 places that way ==> .
0.2 = 20%
X + 1/5y = - 6
subtract x from both sides
1/5y = - x - 6
multiply both sides by 5 to isolate y
y = -5x - 30
