Answer:
31 and 28
Step-by-step explanation:
<u>Let x represent the first number.</u>
<u>Let y represent the second number.</u>
x + y = 59
x - y = 3
<u>Use substitution method to solve.</u>
x = y + 3
y + 3 + y = 59
2y + 3 = 59
<u>Subtract both sides by 3.</u>
2y = 56
<u>Divide both sides by 2.</u>
y = 28
<u>Let's find the second number.</u>
59 - 28 = 31
<u>Check</u>
31 -28 = 3
<u>Answer</u> The two numbers are 28 and 31.
