Answer:

n=5

Step-by-step explanation:

Write an equation

The difference of 3 times a number and six

Difference means subtract. Times means multiply. And means add.

So, 3 times a number, n minus 6

3n-6

Is nine

Is means equal

= 9

3n-6=9

Solve

3n-6=9

Add 6 to both sides

3n-6+6=9+6

3n=15

Divide both sides by 3

3n/3=15/3

n=5

3(4-2x)=-2x will make brainiest to the first two people that answer correctly with explanation

ASHA 777 [7]

Answer:

x = 3

Step-by-step explanation:

First, distribute 3 into the parenthesis:

3(4 - 2x) = -2x

12 - 6x = -2x

Next, combine your x variables by adding +6x to both side:

12 - 6x = -2x (-6x and +6x cancel out)

+6x +6x

12 = 4x (divide 12 by 4 to get x by itself)

/4 /4

x = 3
