How do I use the elimination method to solve two linear equations?
9x+7= 5
11x-7= -2
This problem does not make sense the way you have written it, perhaps it should be:
9x + 7y = 5
11x- 7y = -2
-------------addition eliminates y, find x:
20x + 0 = 3
x = ; divided both sides by 20
:
Find y using the 1st equation
9x + 7y = 5
replace x with 3/20
9() + 7y = 5
() + 7y = 5
7y = 5 -
7y = -
7y =
multiply both sides by 1/7
y = *
y =
