-2(bx-5) = 16

Answer 1

a) x = -3/b

b) x = -1

Explanation:

-2(bx - 5) = 16

a)

-2bx + 10 = 16

-2bx = 16 - 10

-2bx = 6

x = -6/2b

x = -3/b

b)

for b = 3

x = -3/3 = -1

Answer 2

x = -
`(3)/(b)` , x = - 1

Explanation:

given the equation

- 2(bx - 5) = 16 (divide both sides by - 2 )

`(-2)/(-2)` (bx - 5) =
`(16)/(-2)` ( simplify both sides )

bx - 5 = - 8 ( add 5 to both sides )

bx - 5 + 5 = - 8 + 5 ( simplify both sides )

bx = - 3 ( divide both sides by b )

`(b)/(b)` x =
`(-3)/(b)` , that is

x = -
`(3)/(b)`

substitute b = 3 and evaluate for x

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