Question

Find the solution for -0.5x-3.69 = x -1.9 -2.39.

a) x=0.4
b) x= -0.4
c) x=2.5
d) x= -2.5​

Answer 1

`- 0.5x - 3.69 = x - 1.9 - 2.39`

Transpose the values

`- 0.5x - x = 3.69 - 1.90 - 2.39`

Evaluate

`- 1.5x = 3.69 - 4.29`

`- 1.5x = - 0.6`

`x = ( - 0.6)/( - 1.5) * (10)/(10)`

`x = (6)/(15) = (2)/(5)`

or

Answer: a)

`x = 0.4`

Answer 2

a)x=0.4

Explanation:

-0.5-3.69=x-1.9-2.39

-3.69+1.9+2.39=x+0.5x

-3.69+4.29=1.5x

0.6=1.5x

x=0.6/1.5

x=0.4
