Step-by-step explanation:
$400 is 100% of the price
25% is a quarter of 100%
A quarter of 400 is 100 so the discount was $100
400-100 =300
Answer:
y = 4/3
x = 2
Step-by-step explanation:
2x − 3y = 2
x = 6y − 5
x - 6y = -5
2x − 3y = 2 | ×1 |
x - 6y = -5 | ×2 |
2x − 3y = 2
2x - 12y = -10
____________--
9y = 12
y = 12/9
y = 4/3
2x − 3y = 2
2x - 3(4/3) = 2
2x - 4 = 2
2x = 2 + 4
2x = 6
x = 6/3
x = 2
