2x + 7y = 4.....multiply by 2
-4x - 3y = 14
------------------
4x + 14y = 8 (result of multiplying by 2)
-4x - 3y = 14
----------------add
11y = 22
y = 2
2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = 4 - 14
2x = - 10
x = -5
solution is : (-5,2)
Just like simplifying any other fraction.
Divide the top number and bottom number
by their greatest common factor.
The greatest common factor of 40 and 2 is 2 .
