Step-by-step explanation:
An equation is sometimes one solution because it can also have infinitely many solution or no solutions.
Substitute (-11) in for x. You will get 2(-11)-19. Then, use the order of operations to get -22-19=
-41.

Let “x” represent the cost of the dryer in dollars
The washer costs 3x dollars
3x + x = 1000
4x = 1000
x = 250
The dryer is $250
