Question

Solve for x: −5|x + 1| = 10

x = 0
x = −3 and x = 1
x = −1 and x = 3
No solution

Answer 1

Hint by definition |x + 1| is positive

Answer 2

these confuse me

Answer 3

−5|x + 1| = 10
|x + 1| = 10/-5 = -2


so?

Answer 4

the vertical lines mean the absolute value of x+1 which must be positive

Answer 5

absolute value is the positive value
