Question

if x=2t and y=t/3-1 then for what value of t, x=2y​

Answer 1

Answer:

$given \: x = 2t \: (equ \: 1) \\ y = \frac{t}{3} - 1 \:( equ \: 2)\\ x = 2y \: (equ \: 3) \\ substitute \: equ \: 3 \: in \: equ \: 2 \\ 2y = 2t \: (equ \: 4) \\ substitute \: (equ \: 2) \: in \: (equ \: 4) \\ y = t \\ \frac{t}{3} - 1 = t \\ \frac{t - 3}{3} = t \\ t - 3 = 3t \\ 3t - t = - 3 \\ 2t = - 3 \\ t = \frac{ - 3}{2} \\ hope \: it \: helps \: u \: :)$
