Question

Two integers have sum of 42 and a difference of 22. The greater of the two integers is
a.31
b.32
c.22
d.25

Answer 1

so this is solving equations simultaneously

let the integers be x and y

x + y = 42
x - y = 22

add the 2 equations, this will eliminate y... and allow you to solve for x.
