Step-by-step explanation:

(X + y = 26) (-3)

3x + y = 56

____________

- 3 x - 3y = - <u>78</u><u> </u><u> </u><u>Note</u>:cross <em>3x</em> and<em>-3x</em> from both equations (they're opposite)

3x +y =56

____________

-3y +y = - 78 +56

-2y = - 22

y =  \frac{ - 22}{ - 2}  = 11

____________

So we replace y in eq 2: (to obtain x)

3x + 11 =56

3x =45

X =15
