Equation 1) 2x - 3y = -1
Equation 2) y = x -1
Rearrange equation 2 so that x and y are on the same side. To do so, you subtract x from both sides.
2) -x + y = -1
1) 2x - 3y = -1
Multiply ALL of equation 2 by 2.
2) 2(-x + y = -1)
Simplify.
2) -2x + 2y = -1
1) 2x - 3y = -1
Add equations together.
-y = 0
So, y = 0
Plug in 0 for y in the first equation.
2x - 3y = -1
2x - 3(0) = -1
Simplify.
2x - 0 = -1
2x = -1
Divide both sides by 2.
x = -1/2
(-1/2 , 0)

Step-by-step explanation:
Answer: False.
Step-by-step explanation:
The probability for any event = 
Definition : A simple event is an event that has only one possible favorable outcomes.
If we toss a coin and roll a die .
The possible outcomes for event "tossing tails and rolling a 4 or 6" = {(T, 4) , (T,6)}
Since this event has 2 possible favorable outcomes , Therefore it is not an simple event.
Hence, the given statement is "false".
