Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
[tex]4x = 1x + 15 \\ 4x - 1x = 15 \\ 3x = 15 \\ \frac{3x}{3} = \frac{15}{3} \\ x = 5[/tex]
x=5
[tex]4x = 1x + 15 |collect \: like \:terms | \\ 4x - 1x = 15 |simplify| \\ 3x = 15 |divide \:both \: side \: by \: 3 | \\ \frac{3x}{3} = \frac{15}{3} |simplify| \\ x = 5[/tex]
