2/3x = -5/2y + 2
2/3x + 5/2y = 2 (when one unknown goes over to the other side, it changes its sign - 5/2y was negative, but when it went to the left, it became positive)
now, you can multiply both sides by 6 (because it is GCF for denominators 3 and 2) to get rid of fractions
6*2/3x + 6*5/2y = 6*2
4x + 15y = 12
So the correct answer is A. 4x + 15y = 12

Step-by-step explanation:
Answer:
$69
Step-by-step explanation:
A phone sells for $245 it is now on sale for 1/5 off the original price. Find the sale price:
April has a coupon for a extra 10% off the sale price. Find how much will April pay using her discount coupon:
Therefore, April will pay
less.
Interest I = PRT /100
P = $ 1000
R = 5.5% per annum
T = 18 months = 18 /12 = 1.5 years.
I = 1000 * 5.5 * 1.5 /100
I = $ 82.5
Amount = P + I = 1000 + 82.5 = 1082.5.
Hence the it would have grown to $1082.5
