Answer:x=1 y=2
Step-by-step explanation:
you add and get 8x=8 x=1 so plugging in one you get 5+2y=9 so 4=2y so y=2
What is the first step to solving a system of linear equations algebraically?
Answer:
The relationship between the cost/mass is $2.25/kg.
Step-by-step explanation:
You first need to divide $4.50 / 2, to know what a single kilogram mass costs.
$4.50 / 2 = $2.25

$4.50 + $2.25 is $6.75, + another $2.25 = $9.00, and so on.
Answer:
Step-by-step explanation:
plug in the points minus the constant for 7=3*4 + x and you will get -5 for your constant
y=3x - 5
