Question

1. Given s = 3x +t/r

Answer 1

Answer:

Step-by-step explanation:

1). s = $\frac{3x+t}{r}$

   r.(s) = $r.(\frac{3x+t}{r})$

   rs = 3x + t

   rs - t = 3x

   $\frac{rs-t}{3}=\frac{3x}{3}$

   $\frac{rs-t}{3}=x$

   $x=\frac{1}{3}(rs-t)$

2). 5ax + b = c

   (5ax + b) - b = c - b

   5ax = c - b

   $\frac{5ax}{5a}=\frac{c-b}{5a}$

    x = $\frac{1}{5}(\frac{c-b}{a})$
