Respuesta :
two solutions exist,
2(x - 1) = 8
2x - 2 = 8
2x = 10
x = 5
&
2(x + 1) = 8
2x + 2 = 8
2x = 6
x = 3
the two solutions are 5 and 3
2(x - 1) = 8
2x - 2 = 8
2x = 10
x = 5
&
2(x + 1) = 8
2x + 2 = 8
2x = 6
x = 3
the two solutions are 5 and 3
The two solutions of the equation are 7 and -5
What is solution of an equation ?
It is an assignment of value to the unknown variables that make the equality in the equation true
2|x − 1| = 8
| x-1 | = 6
mod mean only positive of that number , when it is removes negative of that will also considered
there will exist two solutions of that equation
1 ) x-1 =6
x= 7
2) -(x-1) =6
-x + 1 =6
x = -5
The two solutions of the equation are 7 and -5
