[tex]\text{Let the number be x,}\\\\~~~~~~4x =x+18\\\\\implies 4x -x = 18\\\\\implies 3x = 18\\\\\implies x = \dfrac{18} 3\\\\\implies x = 6.\\\\\text{The number is 6.}[/tex]

Answer:

6

Step-by-step explanation:

Let the number be " x ".

Four times a number,

4*x = 4x

Number increased by 18,

x + 18

Four times a number is equal to the number increased by 18,

4x = x + 18

Step 1 : Subtract x on both sides

4x - x = 18

3x = 18

Step 2 : Divide 3 on both sides

x = 18/3

x = 6

Hence,

the number is 6.
