Answer:
x= -12 and y=8
Step-by-step explanation:
Let's solve your system by substitution.
−x−y=4;x+2y=4
Step: Solve−x−y=4for x:
−x−y=4
−x−y+y=4+y(Add y to both sides)
−x=y+4
−x
−1
=
y+4
−1
(Divide both sides by -1)
x=−y−4
Step: Substitute−y−4forxinx+2y=4:
x+2y=4
−y−4+2y=4
y−4=4(Simplify both sides of the equation)
y−4+4=4+4(Add 4 to both sides)
y=8
Step: Substitute8foryinx=−y−4:
x=−y−4
x=−8−4
x=−12(Simplify both sides of the equation)
Answer:
x=−12 and y=8
There are a total of 6*6=36 outcomes (sums), of which 18 are odd, 18 are even, so the probability of getting an odd sum is 18/36
of the 36 outcomes, there are four fives and three tens, so the probability of getting a multiple of 5 is 7/36
but the four fives are also odd numbers, so we need to subtract 4/36
the result is: 18/36 +7/26 -4/36=21/36=7/12 =0.58333333
