Three times a number, X, increased by four is equal to five times the number, x. Which equation can be used to solve for x
WITCHER [35]

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
