Answer:
B. Subtract 12 from both sides
Step-by-step explanation:
You must be confused on why I say this. But hold tight, I have an explanation.
Because 12 is on the front side of the minus sign, it is actually positive. That means you must subtract it from both sides.
But what about 4x? Well, it is actually negative! Because the 12 is reduced to zero, the equation is technically 0 - 4x = 42. However, we just remove the 0 to make -4x = 42.
By the way, the fully solved equation is: x = -10.5 or x = -10 1/2
Hope this helps!
