Question 168849
lets call the numbers a and b
:
a+b=-42...eq 1
a-b=52....eq 2

using the elimination method to solve means we try to eliminate one of the variables and we can do that just by adding the 2 equation together(the b terms cancel out.
:
we end up with 2a=10---> divide by 2 and {{{highlight(a=5)}}}
:
to find b just plug a's value into either equation
:
5-b=52--->subtract 5 from each side and divide by -1{{{highlight(b=-47)}}}
