Answer:

How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Ghella [55]

Answer:

$x=-4$

Step-by-step explanation:

So we have the equation:

$3(2x+2)=18+4(x-5)$

Distribute the left and the right:

$3(2x)+3(2)=18+4(x)+4(-5)$

Simplify:

$6x+6=18+4x-20$

Combine on the right:

$6x+6=4x-2$

Subtract 4x from both sides. The right cancels:

$(6x+6)-4x=(4x-2)-4x\\2x+6=-2$

Subtract 6 from both sides. The left cancels:

$(2x+6)-6=(-2)-6\\2x=-8$

Divide both sides by 2:

$(2x)/2=(-8)/2\\x=-4$

Thus, the value of x is -4.
