Question

Find two numbers with a sum of 20 and a difference of 14

Answer 1

write out the statements as algebraic equations and then solve. e.g.:
a + b = 20
a - b = 14

Another way would be to use trial-and-error where you start by "guessing" a solution - e.g. 0 and 14 have a difference of 14 but do not add up to 20, so then try:
1 and 15, then 2 and 16 etc, etc

Answer 2

thankyou

Answer 4

2 and 16 is not the answer, I was just giving examples of how you could use trial-and-error.
