HELP?? If one is added to a number and the sum is tripled the result is 19 more then the number. Find the number. Um?

Respuesta :

The value of x is equal to 8.

3(x + 1) = 19 + x

Distributive property.

3x + 3 = 19 + x

Subtract x from both sides.

2x + 3 = 19

Subtract 3 from both sides.

2x = 16

Divide both sides by 2.

x = 8
