. . . . . . . . .

but that's right- try saying just x= 13 without the 16 or you cant? if you cant ill answer it in the comments

13

Step-by-step explanation:

Cross multiply:

x + 3 * 3 = 6 * 8

Simplifying

x + 3 * 3 = 6 * 8

Reorder the terms:

3 + x * 3 = 6 * 8

Reorder the terms for easier multiplication:

3 * 3 + x = 6 * 8

3 * 3 + x * 3 = 6 * 8

9 + 3x = 6 * 8

Multiply 6 * 8

9 + 3x = 48

Solving

9 + 3x = 48

Move all terms containing x to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + 3x = 48 + -9

Combine like terms: 9 + -9 = 0

0 + 3x = 48 + -9

3x = 48 + -9

Combine like terms: 48 + -9 = 39

3x = 39

Divide each side by '3'.

x = 13

Simplifying

x = 13

c. (3,2,6) is the answer.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
