3 were called on Friday.
Then the each of the 3 called 3 others which all equals to 9, since 3*3 is 9.
Now, each of the 9 called 3 others on Sunday which altogether equals 27, since 9*3 is 27. Therefore, the answer is 27.
Every time the word each is used in a math problem, that would mean that you need to multiply something. And that's what happened here
Y = x + 6
y = -3x + 6
put the system of linear equations into standard form
x - y = -6
-3x - y = -6
solution:
x = 0
y = 6
-12x = 12x
Start by moving all the terms with the variable you want to solve for on one side of the equation and the rest on the other side of the equation.
We will move 12x to the left side of the equation by subtracting 12x from both sides. Now your equation should look like:
-24x = 0
Isolate the variable x by dividing both sides by -24. Everything divided by 0 is equal to 0, so that means x will be equal to 0.
x = 0
Your answer is x = 0.
