this is system of equations
2x + 5y = -1 times this one by 5 to make the y's opposite
-10x -25y = 5
10x - 25y = -5 (this is it times by 5, now add them)
__________
0 + 0 = 0
now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.

Answer:
Step-by-step explanation:
The probability of getting one even and one odd is the sum of probability of getting even and of getting odd and even. Since there are 3 even or odd on each die out of six numbers you have
P(EO)(3/6)(3/6)=1/4 and P(OE)=(3/6)(3/6)=1/4 so 1/4+1/4= 1/2
or you can find the probability of getting two odds or two evens and subtract that from 1
P(EE)=(3/6)(3/6)=1/4, P(OO)=(3/6)(3/6)=1/4
P(EO)=1-1/4-1/4=1/2
