so we have to write the equations in standard form.

x+y=112 is good

let's fix y=x-58

to write it in standard form we have to subtract x from the other side

x-y=58

now we can combine them

x + y = 112
x - y = 58

now you just add going down

2x= 170

170/2x = x = 40.

i think 40 is the answer

Answer:

x=85

y=27

;)

Explanation:

x+y=112

y=x-58

add 58 to the other side

58+y=x

Subtract y

x-y=58

x+y=112

Now if we add these we get

2x=170

x=85

Then if we substitute 85 in x+y=112

85+y=112

112

-85

____

27

Check your Answer on

y=x-58

27=85-58

27=27

This is the Answer

Please DM me if I should reexplain THANK YOU!
