[ Explanation ]
4(y + 6) - 2(y - 2)
[Expand] 4(y + 6): 4y + 24
4y + 24 - 2(y - 2)
[Expand] -2(y - 2): -2y + 4
4y + 24 - 2y + 4
[Simplify] 4y + 24 - 2y + 4: 2y + 28
= 2y + 28
Jace's song were played on 8 commercials and 2 movies
<h3>Further explanation</h3>Simultaneous Linear Equations could be solved by using several methods such as :
- <em>Elimination Method</em>
- <em>Substitution Method</em>
- <em>Graph Method</em>
If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.
Let us tackle the problem!
<em>Let:</em>
<em>Number of Commercials = C</em>
<em>Number of Movies = M</em>
<em>Jaces songs were played on 6 more commercials than movies.</em>
→ <em>Equation 1</em>
<em>Jace will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie.</em>
<em>His total earnings in the royalties from all commercials and movies was $680.</em>
→ <em>Equation 2</em>
<em>Equation 1 ↔ Equation 2 :</em>
The number of commercials and the number of movies in which Jaces songs where played is respectively 8 and 2
