Answer:
Explanation:
the good part about this one is if u look, u can see that u have a positive 5x and a negative 5x....when added, these will cancel out....so u dont have to multiply ur equations by anything, u just have to add them
5x - 6y = 6
-5x + 4y = -14
---------------------add
-2y = - 8
y = -8/-2
y = 4
now sub 4 in for y in either of the original equations
5x - 6y = 6
5x - 6(4) = 6
5x - 24 = 6
5x = 6 + 24
5x = 30
x = 30/5
x = 6
lets check it...
-5x + 4y = -14
-5(6) + 4(4) = -14
-30 + 16 = -14
-14 = -14 (correct)
so it checks out.....x = 6 and y = 4 or (6,4) <===
