Question

Evaluate the equation.

18.3 - b = 2.3
A. b = 15
B. b = 16
C. b = 20.6
D. b = 21.6

Answer 1

To solve the equation 18.3 - b = 2.3, we subtract 18.3 from both sides, resulting in -b = -16. Multiplying both sides by -1, we find that b = 16.

Step-by-step explanation:

To evaluate the equation 18.3 - b = 2.3, we need to isolate the variable b. We do this by subtracting 18.3 from both sides of the equation, which gives us:

• 
  
• -b = 2.3 - 18.3
• 
  
• -b = -16

To find the value of b, we multiply both sides by -1:

• 
  
• b = 16

The answer is B. b = 16.
