Answer:
[tex]x=\frac{55}{7}[/tex]
Step-by-step explanation:
we have
[tex]\frac{4}{7}=\frac{x-1}{12}[/tex]
solve for x
Multiply in cross
[tex](4)(12)=(7)(x-1)[/tex]
Divide by 7 both sides
[tex]\frac{48}{7}=x-1[/tex]
Adds 1 both sides
[tex]\frac{48}{7}+1=x[/tex]
[tex]\frac{55}{7}=x[/tex]
Rewrite
[tex]x=\frac{55}{7}[/tex]
