Make t the subject of the formula <br> P= 3-2t<br> —————<br> 4+t

Rufina [12.5K]

Answer:

$t = \frac{3 - 4p}{p + 2}$

Step-by-step explanation:

Given

$P = \frac{3 - 2t}{4 + t}$

Required

Make t the subject

$P = \frac{3 - 2t}{4 + t}$

Cross Multiply

$P * (4 + t) = 3 - 2t$

$4p + tp = 3 - 2t$

Collect Like Terms

$tp + 2t = 3 - 4p$

Factorize:

$t(p+2) = 3 - 4p$

Make t the subject

$t = \frac{3 - 4p}{p + 2}$
