Two times a number x minus six times another number y is negative six. Negative two times a number x plus five times another number y is eighteen.
Write the system of equations.

Step-by-step explanation:

Translating the phrase into an equation, we get:

And:

So the system of equations would be:

If you want to put it into slope-intercept form, you can simplify both equations:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

it is 10.6 according to my calculations
