Question 1196459
<br>
The solution from the other tutor is valid (or at least it might be; I didn't bother to check).<br>
But it is not a very smart solution method.  Why solve the first equation for x and then substitute in the second equation when the second equation is already solved for y?<br>
Instead, simply substitute y=-2x-13 (from the second equation) in the first equation.<br>
x+2(-2x-13) = -2
x-4x-26 = -2
-3x = 24
x = -8<br>
Then use the given second equation to find y.<br>
y = -2(-8)-13 = 16-13 = 3<br>
ANSWER: (x,y) = (-8,3)<br>
