[tex] W + D = 1000 \\
W = 3*D [tex]
Plug the second equation into the first;
[tex] W+D=1000 \\
(3*D)+D=1000\\
4D=1000 [tex]

D = $250

Let the cost of the dryer be x.

Since the washer is 3* the cost of dryer = 3*x = 3x

The total cost = $1000

x + 3x = 1000

4x = 1000

x = 1000/4

x = 250

Since the cost of the dryer be x ,   x = 250

Cost of dryer = $250.

Hope this explains it.

27x + 24y= 4.5<br><br> 1.5x + y =0.225
Goryan [66]

Answer:

x = 0.1, y = 0.075

Step-by-step explanation:

Given the 2 equations

27x + 24y = 4.5 → (1)

1.5x + y = 0.225 → (2)

Multiplying (2) by - 24 and adding to (1) will eliminate the y- term

- 36x - 24y = - 5.4 → (3)

Add (1) and (3) term by term to eliminate y

- 9x = - 0.9 ( divide both sides by - 9 )

x = 0.1

Substitute x = 0.1 into either of the 2 equations and solve for y

Substituting into (2)

1.5(0.1) + y = 0.225

0.15 + y = 0.225 ( subtract 0.15 from both sides )

y = 0.075

Okay. For these types of problems, you must do order of operations (PEMDAS). Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. Mind you that you do these steps from left to right, and multiplication and division is done from left to right. Same thing with addition and subtraction. With that being said, here are your answers if you do the expressions correctly.
