3[-x+(2x+1)]=x-1 can anyone solve this?

x=-2

Step-by-step explanation:

3[-x+(2x+1)]=x-1

3[-x+2x+1]=x-1

-3x +6x +3= x-1

3x-x=-1-3

2x=-4

x=-4/2

x=-2

what are the options? ?

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
