Answer: i believe what you're looking for is W so, W=3

Step-by-step explanation: you add +7 to each side of the equation, which gives you W=3

Answer:

w= 3

Step-by-step explanation:

Add 7 to both sides of the equation  w-7 = -4

w-7+7=-4+7

Simplify : w-7+7=-4+7  which simplifies to w=   -4 +7

So, w  =  -4 +7  is w= 3
