-y + 7 = 13
-y = 6
y = -6
(3, -4)
It is an equation and the value of y is 18
x = 3, y = -4
x = 3 and y = -4
If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13
4x - y = 1 3x + y = 13 Simultaneous Equations. Add ; This will eliminate 'y' Hence 7x = 14 x = 2 When x = 2 3(2) + y = 13 6 + y = 13 y = 13 - 6 y = 7 Hence the solution in ( x,y) form is ( 2, 7).
(3, -4)
yes.

If you mean: y=6+x/ x=7 Then that is the equation for a line. Put in any number for "x" and "y" will always be 6 more than that. In this case, y=13
Y+7=9 equals 2+7=9.
It is consistent because x = -13 and y = -45
