Answer:
the dryer costs $450
step-by-step explanation:
w + d = 831
w = d-69 (they told us we will have to take $69 from the cost of the dryer to determine the cost of the washer)
(d-69) + d = 831
Let's combine like terms
2d - 69 = 831
add 69 to both sides to solve for d
2d = 900
divide both sides by 2 to solve for d
d = 450; the dryer costs $450
Here’s how I like to do standard forms:
It’s really easy! Just plug everything in.
(X-intercept)y + (y-intercept)x = (x-intercept x y-intercept)
For your numbers =
7y + 4x = 28
Check it on an online grapher, it works!
