Question

Is the equation a true statement when x = 3? In other words, is 3 a solution to theequation?3x + 2 = 11A. Yes, 3 is a solution to the equation.B. No, 3 is not a solution to the equation.

Answer 1

The given equation is:

`3x+2=11`

Calculate the value of x

First move 2 to the left hand side and change its sign

`3x=11-2`

Calculate the difference

`3x=9`

Divide both sides by 3

`(3x)/(3)=(9)/(3)`

This gives:

`x=3`

Therefore the statement is true when x=3 hence 3 is a solution
