13
If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13
x = 3, y = -4
If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18

2x plus 3y
There are infinitely many ordered pairs tat are solutions. They are all points on the line represented by 5x-6y = 13
x = 3, y = -4
If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18

273 13+8 = 21 and 13*21 = 273
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
basically you asked what -28+21 which equals -7
