Answer:
Guitarist wtote 25 songs
Drummer wrote 10 songs
Step-by-step explanation:
G: number of guitarist songs
D: number of Drummer songs
We have:
G=3D - 5 (The guitarist wrote 5 fewer than three times the number of songs that the drummer wrote)
G+D=35 (They wrote a total of 35 songs)
That is the meaning of each equation.
Now we have to solve these system of equations:
G=3D-5
G+D=35
Using the substitution method:
(3D-5)+D=35
4D=35+5
4D+40
D=10
Thus: G=35-10
G=25
