Question

The sun of 2 numbers is 39 and their difference is 5. What is the larger number? Please also explain HOW TO get that answer!!!! PLSSS ‍♀️

Answer 1

Sum means add
x+y=39
difference is 5
x-y=5
so we do this
x-y=5
add y to both sides
x=5+y
subsitute 5+y for x
5+y+y=39
add like terms
5+2y=39
subtract 5
2y=34
divide by 2
y=17
subsitute
x=5+y
x=5+17
x=22

the larger number is 22
