Answer:
The answer is 4
Explanation:
The lines around 2b-5 means you have to find the absolute value of that expression. The absolute value is how far a number is from zero on a number line. Basically the absolute value is the same number but positive. So if b=1 then 2×1-5 = -3 but because of absolute value, it would be (Positive) 3. 3+1=4
