Use the method pemdas and you get x=28
Ok so for starters you want to choose an equation and solve for a variable.
So, I am going to choose x from the first equation.
Add y to both sides and you get x=11+y
Next, substitute 11+y for x in the other equation so you get...
2(11+y) +10y=-6
Next distribute the 2 throug the 11 and the y
22+2y+10y=-6
12y=-28
y=-28/12
reduce this fraction to make this easier.
y=-7/3
Now plug in why to either of the equations to find x
x-(-7/3)=11
x+7/3=11
x=11-(7/3)
x=(33/3)-(7/3)
x=26/3
so x = 26/3 and y = -7/3
you can also check to see if this is correct by substituting each of these values into the equations.
Answer:
Variable 
represents the slope of the equation.
Step-by-step explanation:
Given that the administrative fees that company charge is $3.50.
Also, the Zhao has a bill of $63.25.
The equation used by Zhao is
We can compare the equation of a line in the slope-intercept form.
We can see the y-intercept is $3.50 that is a fixed cost. And the company charged $63.25 that is the dependent variable.
Also, variable that is the rate per kilowatt-hour (kWh) represents the slope of the equation.
there is 1 number 3 on a 6 sided die
so the probability or rolling a 3 is 1/6
