Question

Solve for x: 4 over 7 equals the quantity x minus 1 end quantity over 12

Answer 1

Answer:

$x=\frac{55}{7}$

Step-by-step explanation:

we have

$\frac{4}{7}=\frac{x-1}{12}$

solve for x

Multiply in cross

$(4)(12)=(7)(x-1)$

Divide by 7 both sides

$\frac{48}{7}=x-1$

Adds 1 both sides

$\frac{48}{7}+1=x$

$\frac{55}{7}=x$

Rewrite

$x=\frac{55}{7}$
