First, let's write the equation.
Ten times a number -- 10x
16 more -- 10x - 16
Twice the number -- 2x
10x - 16 = 2x or 10x = 2x + 16
Let's use the first one: 10x - 16 = 2x
First, let's isolate the x to one side.
10x - 16 = 2x
-10x -10x
-16 = -8x
Now, let's multiply each side by -1 to make them positive
-16 = -8x
*-1 *-1
16 = 8x
Finally, let's divide each side by 8
16 = 8x

8 8
Our answer is 2 = x
This means that the number is 2.
I hope I helped!

Answer:
250 students
Step-by-step explanation:
Let the number of sixth grade students be represented by = x
We were told that:
At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. 100 sixth-grade students prefer hip hop music.
Hence:
40% of x = 100
40/100 × x = 100
40x/100 = 100
Cross Multiply
40x = 100 × 100
x = 10000/40
x = 250
The number is sixth-grade students is 250 students
