Option B. 8
7+3 = 10
18-10 = 8
I believe the correct answer is -2
Answer:
b = 14
Step-by-step explanation:
9 + (5-b) = 0
9 + 5 - b = 0
14 - b = 0
+ b = + b
14= b
you need to isolate the variable so in order to do that you need to subtract 8 from both sides of the equation as so:
8 - x/10 - 8 = -11 - 8 simplify -x/10 = -19
isolate the variable -10/1 x -x/10 = -19 x -10/1 simplify
x = 190
