Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
Given:
[tex]DG = 10[/tex]
See attachment for complete question.
From the attachment, we can conclude that:
[tex]x + 1 + 2x - 15 = DG[/tex]
Substitute 10 for DG
[tex]x + 1 + 2x - 15 = 10[/tex]
Collect Like Terms
[tex]x + 2x = 10 + 15 - 1[/tex]
[tex]3x = 24[/tex]
Solve for x
[tex]x = 24/3[/tex]
[tex]x = 8[/tex]
