What is the value of x in the solution to the system of linear equations?
xenn [34]
Since y=x-4 you would simply just plug that into 'y' on the other equation, given: x-4=3x+2.
Subtract x from both sides, it will leave you with -4=2x+2.
Next you would subtract 2 from both sides, leaving you with -6=2x.
All you need now is to get rid of the coefficient in front of 'x' so you divide both sides with 2, leaving you with your answer: -3=x.

Answer: -3=x

Hope this helps!

The mean of six numbers is 10. When
vivado [14]

Answer:

3

Step-by-step explanation:

If 6 numbers have a mean value of 10, it means that the sum of the numbers divided 6 is equal to 10. This can be expressed as:

x÷6=10

x=60

The new number added will be the 7th number and now the mean is 9. You have to ask what number divided by 7 is equal to 9? This can be expressed as:

y÷7=9

y=63

63-60=3

So the new number added is 3
