Question

Hey i was wondering can i move +7 from inside the absolute value in the left side to -7 outside the absolute value on the right side? for example in the question below is the answer right is the answer zero ?

Answer 1

`\rm |x + 7| = - 4`

The statement is false for any value of x because the absolute value function is always positive or 0.

• Thus, The equation has zero solutions!!~

Answer 2

• A) Zero

Explanation:

Given equation:

• |x + 7| = - 4

The left side is absolute value, we know it is zero or positive value but never negative.

The right side is negative so the equation can't have solutions as we have contradiction above.
