exoexoexo · Answer

use the equation 2(x+8)=(x+22)

exoexoexo · Answer

anonymous · Answer

is it x = 6

anonymous · Answer

so then it would be 12 years in time?

$W_o = 8$
$J_o = 22$


$W(t) = W_o + t \ = 8 + t$

$J(t) = J_o + t \ = 22 + t$


$J(t) = 2 W(t)  \ \implies 22 + t = 2( 8 + t)  \ \implies t = 6$

check 
$W(6) = 14$
$J(6) = 28$

$J =2 \times W$  $\Large  \checkmark$

$$2(x+8)=(x+22)$$
$$2x+16=x=22$$
$$2x+16-16=x+22-16$$
$$2x=x+6$$
$$2x-x=x-x+6$$
$$x=6$$
so the answer is 6 years
