Question

Solve w+ 3 = -4.
w= -7
Which statement shows the correct justification for the step used to solve the equation?
Add 4 to each side.
Add 3 to each side.
Subtract 4 from each side.
Subtract 3 from each side.

Answer 1

The answer would be to subtract 3 from each side.

Answer 2

Answer

Subtract 3 from each side

Step-by-step explanation

In the equation:

$w + 3 = - 4$

Subtracting 3 from both sides of the equation. We have:

$w + 3 - 3 = - 4 - 3 \\ w + 0 = - 7$

Therefore: $w = - 7$

The simplest way to do this is by moving 3 to the other side of the equation, where it then changes to -3 due to the equality sign (=). this is what I mean:

$w + 3 = - 4 \\ w = -4 - 3 \\ w = - 7$
