Answer 2

Step-by-step explanation:

Given Construct a word problem on simultaneous equations in two variables(on age,rupees,metres,speed,etc),so that value of one variable will be 18

• Let the ages of two people be a and b
• The sum of ages of two people is 38
• Hence a + b = 38
• So a + b – 38 = 0----------1
• Now the difference between them is 2.
• So a – b = 2
• So a – b – 2 = 0-----------2
• subtracting 1 and 2 we get
• 2b – 36 = 0
• 2b = 36
• Or b = 18
• Now a – 18 = 2
• Or a = 18 + 2
• Or a = 20
• Therefore their ages are 18 and 20
