The sign in the second equations are not clear (i.e. not visible).  They make a big difference.
You can get the answer by substituting x in each equation and see if you get the right value of y.

anonymous · Answer

6x-2y =12

mathmate · Answer

Sorry, don't see the sign of the first either.

anonymous · Answer

it is minus as well: y=3x-7

mathmate · Answer

y=3x-7  => 3x-y=7 => 6x-2y = 14
Compare with 6x-2y=12
what do you see, and what do you conclude?

No Algebraic Solution
solution
1. The value of a variable that makes an equation true. 2. In chemistry, a solution is a homogeneous mixture composed of only one phase.

mathmate · Answer

We're maths here, so no (algebraic) solution is correct.
