B. 7
Step-by-step explanation:
4(x-3)=16 so you have to multiply the entire equation by 4 since it is outside parenthesis
4x-12=16 then you have to add 12 to both sides to isolate 4x
Β Β +12 Β +12
4x=28 then you have to divide both sides by Β to just have x
4/4=1 Β 28/4=7 (the 1 doesn't mater because 1x=x and x=1x)
x=7 is your answer
