Answer:
x= [tex]\frac{y-1\\}{3}[/tex]-4
Step-by-step explanation:
1. Move the equations
-3(x+4)= y-1
2. divided both of them by -3
[tex]\frac{-3(x+4)}{-3} =\frac{y}{-3} - \frac{1}{-3}[/tex]
x+4[tex]=-\frac{Y-1}{3}[/tex]
3. subtract 4 on both
[tex]x+4-4=-\frac{Y-1}{3}-4[/tex]
4.Simplify
[tex]x=-\frac{Y-1}{3}-4[/tex]
~~~Hope this helps~~~ :)
