How do you solve the system of equations #-16x - 4y = 12# and #- 4x + y = - 11#?
1 Answer
Explanation:
Given 2 equations, let us number them
we can simplify this equation by 4 , it would be easier for solving
the two equations are:
First we add both equations :
second, let us substitute the value of
Third, check if the values
therefore,x=1 and y=-7#
