Question

How many solutions does -4x-5=4x+11 have?

Answer 1

one solution, x = - 2

Explanation:

given the equation

- 4x - 5 = 4x + 11 ( subtract 4x from both sides )

- 4x - 4x - 5 = 4x - 4x + 11 ( simplify both sides )

- 8x - 5 = 11 ( add 5 to both sides )

- 8x - 5 + 5 = 11 + 5 ( simplify both sides )

- 8x = 16 ( divide both sides by - 8 )

`(-8)/(-8)` x =
`(16)/(-8)` , that is

x = - 2
