Question

Solve the equation for the given variable k/3-11=-20

Answer 1

`(k)/(3-11)` = - 20

You can subtract the numbers in the parenthesis:
(3-11) = (-8)

Multiply the denominator to both sides so it cancels out and isolates the variable
`(k)/(-8)` × -8 = - 20 × -8
-8 and -8 cancels out

k = 160

Quick check:

`(160)/((3-11))` = -20

`(160)/(-8)` = - 20
- 20 = - 20
Yes its right

the answer is: k =160
