please explain how to do this

Solve the system by the elimination method.
x + y - 6 = 0
x - y - 8 = 0
When you eliminate y , what is the resulting equation?

2x = -14
2x = 14
-2x = 14

anonymous · Answer

2x=14, because you add downward, and then in all the answers the 14 is on the left, so you add the 14

da_scienceman · Answer

please add both equatrions to get 2x=14. Then x = 14/2=7.

da_scienceman · Answer

Then just substitute for x in any of the equations to get y!

$\begin{array}{llll}
x &+ y &- 6 &= 0\
x &- y &- 8 &= 0\
\hline\
2x&+0y&-14&=0\implies 2x-14=0
\end{array} $
