Question 196374: can you find the two linear equations by addition for me?
here is the question:
7/3x-y=-4
1/4x-1/3y=7/4

You can put this solution on YOUR website! 7x/3-y=-4
x/4-y/3=7/4 mulltiply this equation by -1/3 & add.
-7x/9+y/3=4/3
-------------------------
x/4-7x/9=7/4+4/3
(9x-4*7x)/(4*9)=(7*3+4*4)/4*3)
(9x-28x)/36=(21+16)/12
37x/36=37/12
37x*12=37*36
12x=36
x=36/12
x=3 ans.
7*3/3-y=-4
21/3-y=-4
7-y=-4
-y=-4-7
-y=-11
y=11 ans.
