Answer:

Step-by-step explanation:

Three times a number x : 3x

Three times a number x increase by 4: 3x +4

Five times the number x: 5x

5x = 3x +4

Subtract 3x from both the sides.

5x - 3x = 3x +4 - 3x

2x = 4

Divide both sides by 2

2x/2 = 4/2

x=2

The number is 2

Answer:

The value of $x$ :

$x = 16$

Step-by-step explanation:

-To find the value of x, you need to use $3x + 18$ and $66\textdegree$ written as in equation like this:

$3x + 18 = 66$

-Then, you solve for it:

$3x + 18 = 66$

$3x + 18 -18 = 66 -18$

$3x = 48$

$\frac{3x}{3} = \frac{48}{3}$

$x = 16$

So, therefore the final answer is $x = 16$ .
