3. if 4 is subtracted from twice a number the result is 10 less than the number find the number.4. three times a number divided by two is the number divided by 4 find the number. 5. an integer, n, is added to 2, and that sum is then multiplied by 3. that result is 5 less than the original integer. what is the integer?

3.

2x - 4 = 10

Add 4 to both sides.

2x = 14

Divide both sides by 2.

x = 7

4.

3(x/2) = x/4

Distributive property.

3x/2 = x/4

Convert denominators to a common number.

6x/4 = x/4

Multiply both sides by 4.

6x = x

Subtract x from both sides.

5x = 0

Divide both sides by 5.

x = 0

This equation is equal to 0.

5.

3(n + 2) = n - 5

Distributive property.

3n + 6 = n - 5

Subtract n from both sides.

2n + 6 = -5

Subtract 6 from both sides.

2n = -11

Divide both sides by 2.

n = -5.5

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
