Question

Using truth table, prove that A+(B+C) = (A+B) +C. State the name of the

specified law.​

Answer 1

x+1

x+2

=

3

4

Step 1: Cross-multiply.

x+1x+2=34

(x+1)*(4)=3*(x+2)

4x+4=3x+6

Step 2: Subtract 3x from both sides.

4x+4−3x=3x+6−3x

x+4=6

Step 3: Subtract 4 from both sides.

x+4−4=6−4

x=2

Answer:

x=2
