Question

What is the value of the unknown?
4x?+ ?= -2x?

Answer 1

If the whole transaction is written separately from the beginning, an algebraic equation is obtained

Explanation:

`4x = s`

`- 2x = w`

`w * s = - 8 {x}^(2)`

`w = s = s * s = 16 {x}^(2)`

`- 8 {x}^(2) + 16 {x}^(2) = 8 {x}^(2)`

This is the way to get the answer
