Question 176748
ok our two numbers are x and y
:
x+y=64....eq 1
x-y=4.....eq 2
:
rewrite eq 2 to x=4+y and plug that value into eq 1
:
(4+y)+y=64
:
2y=60.....subtracted 4 from both sides and combined like terms
:
{{{highlight(y=30)}}}divided by 2 on each side to isolate variable y
:
x=4+y{{{highlight(x=4+30=34)}}}
