I think of a number, double it and add eleven. I get twenty five. Using the statement above form an equation using the letter x!

Wittaler [7]

Answer:

2x + 11 = 25

x = 7

Step-by-step explanation:

Let the number be x.

Double of x and add 11 equals 25.

2x + 11 = 25

Solve the equation.

2x + 11 = 25

Subtract 11 on both sides.

2x = 25 - 11

2x = 14

Divide 2 on both sides.

x = 14/2

x = 7
