Answer:
The solution is (2, 4)
Explanation:
Note that if we multiply the second equation by -2, the first term of this revised equation will be -14x, which will cancel out the +14x in the first equation:
14x - 8y = -4 => 14x - 8y = -4
-2(7x + 3y = 26) => -14x - 6y = -52
----------------------
-14y = -56, or y = 4
Substituting 4 for y in the first equation, we get 14x - 8(4) = -4, or
14x = 28 => x = 2
The solution is (2, 4)
