This is how I would solve it:
1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14
To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
65 lbs= 1040 oz
120 people x 6 oz = 720 oz
1040-720 = 320 oz or 20 lbs left
Answer:
Step-by-step explanation:
when x = 5
x² + 8
= (5)² + 8
= 25 + 8
= 33
Let the two numbers be x and y.
Given,
x + y = 7
x = 7 - y
Also given,
x - y = -1
7 - y - y = -1
-2y = -8
y = 4
x = 7 - y = 7 - 3 = 4
Hence, the numbers are 3 and 4.
