he smaller is
71. What are the numbers?
1 answer:
Answer:
Smaller is 5, larger is 14
Step-by-step explanation:
y is larger, x is smaller
2y = 3 + 5x
4y + 3x = 71
Let's solve for y in the first one, then substitute that into the second one.
y = 3/2 + 5/2x
4(3/2 + 5/2x) + 3x = 71
12/2 + 20/2x + 3x = 71
6 + 10x + 3x = 71
13x = 65
x = 5
Substitute that in to the first equation:
2y = 3 + 5(5)
2y = 3 + 25
2y = 28
y = 14
check those answers in the second equation
4y + 3x = 71
4(14) + 3(5)
= 56 + 15 =71
