Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378

The answer is 19 - 4, because of PEMDAS.
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Any expression wrapped in parentheses always comes first. Whether the sky is pink or blue, parentheses still come first.
1.) Fill in y=2x-1 into the first equation
3x-(2x-1)=-1
3x-2x+1=-1
x+1=-1
x=-2
2.) Fill in x=-2 into y=2x-1
y=2(-2)-1
y=-4-1
y=-5
Your answer is (-2,-5) or x=-2 and y=-5
