enote the cost of a dress and y denote the cost of a belt.
A: x = $8, y = $4
B: x = $5, y = $4
C: x = $7, y = $10
D: x = $4, y = $5
1 answer:
Step-by-step explanation:
• 5X + 2Y = 48
• 2Y = 48 - 5X
let's use this and replace it on the second equation
• 3X + 2Y = 32
• 3X + 48 - 5X = 32
• 3X - 5X = 32 - 48
• -2X = -16
• X = 8
now use the X value we found to find the Y
• 5X + 2Y = 48
• 5*8 + 2Y = 48
• 40 + 2Y = 48
• 2Y = 48-40
• Y = 8/2
• Y = 4
A: x = $8, y = $4
