Question

1. Given s = 3x +t/r

rearrange the equation for x, in terms of r, s, and t
2. Given 5ax + b = C, rearrange the equation for x, in terms of a, b, and c.

Answer 1

Explanation:

1). s =
`(3x+t)/(r)`

r.(s) =
`r.((3x+t)/(r))`

rs = 3x + t

rs - t = 3x

`(rs-t)/(3)=(3x)/(3)`

`(rs-t)/(3)=x`

`x=(1)/(3)(rs-t)`

2). 5ax + b = c

(5ax + b) - b = c - b

5ax = c - b

`(5ax)/(5a)=(c-b)/(5a)`

x =
`(1)/(5)((c-b)/(a))`
