Question

How do you solve it

Answer 1

see explanation

Explanation:

(2)

given z = xm

isolate x by dividing both sides by m

`(z)/(m)` = x

(4)

given z = x + m ( subtract m from both sides )

z - m = x

(6)

given - 3a - 4k = - 1

add 4k to both sides

- 3a = 4k - 1 ( to isolate a divide both sides by - 3 )

a =
`(4k-1)/(-3)` = -
`(4k-1)/(3)`

(8)

given z = - 4a ( divide both sides by - 4 )

a = -
`(z)/(4)`
