A drummer and a guitarist each wrote songs for their band. The guitarist wrote 8 fewer than twice the number of the songs that the drummer wrote. They wrote a total of 46 songs. Which system of equation model this situation if the drummer wrote d songs and the guitarist wrote g songs?

Respuesta :

Answer:

G=2d-8 G + D=46

Step-by-step explanation:

We want to write and solve a system of equations to model the given situation.

g = 2*d - 8

g + d = 46

The first thing we need to do, is define the variables we will be using.

  • g = number of songs that the guitarist wrote.
  • d = number of songs that the drummer wrote.

From "The guitarist wrote 8 fewer than twice the number of the songs that the drummer wrote."

We can write:

g = 2*d - 8

And we know that in total they wrote 46 songs, so we can also write:

g + d = 46

Then the system of equations is:

g = 2*d - 8

g + d = 46
