B - 8x
To find this, combine like terms.
8x - 2x is 6x, then add the two x's on the side to bring it back to 8x.
Hope this helps!
Which variable are we solving for?
For y:
y= 5x-4/ 13
For x:
x= 13y+4/ 5
we are given
system of equations
First equation is

Second equation is

now, we can find augmented matrix

now, we can change it into reduced row echelon form
step-1: multiply the 1st row by 1/3

step-2:add -3 times the 1st row to the 2nd row

step-3:multiply the 2nd row by 1/4

step-4: add 2/3 times the 2nd row to the 1st row

so, we get

Answer is (5,-8)
Answer:
