Best ResponseYou've already chosen the best response.0First you decide which variable is to be substituted, x oy. In this case you can solve for x in the first equation alone: 2x + 0y=14 obviously x=7 It means we now we have a value to substitute for x in the second equation x+11y = 18 substituting the value 7 for x we get 7+11y = 18 Now simply solve for y subtracting 7 from both sides getting: 11y=11 making y=1.
