I would but my teacher has a ad blocker on and I cant access the attachment :P
I don't know if i'm right or what because I haven't learned binomial in like almost 4 years. (3x+y)?
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:
4
Step-by-step explanation:
$2x=$8
x=$8÷$2
x=4
We know 1 package cost $2, $2+$2+$2+$2=$8
4times $2 equal to $8
