<u>Step 2: Solve for </u><em><u>x</u></em>
- [Multiplication Property of Equality] Cross-multiply:

- [Division Property of Equality] Divide 5 on both sides:

--------------------------------------------------------------
Define x :
--------------------------------------------------------------
Let the dryer be x.
Dryer = x
Washer = x -53
--------------------------------------------------------------
Construct Equation :
--------------------------------------------------------------
The washer and the dryer cost $847
⇒ x + x - 53 = 847
--------------------------------------------------------------
Solve x :
--------------------------------------------------------------
x + x - 53 = 847
2x - 53 = 847
2x = 847 + 53
2x = 900
x = 450
--------------------------------------------------------------
Find cost of dryer and washer :
--------------------------------------------------------------
Dryer = x = $450
Washer = x = 450 - 53 = 397
--------------------------------------------------------------
Answer: Dryer = $450

Answer:
1. Slope = 42.667/2.000 = 21.333
2. x-intercept = 6/64 = 3/32 = 0.09375
3. y-intercept = 6/-3 = 2/-1 = -2.00000
