Question

Solve for k k/2 + 1/2 = 3

Answer 1

k/2+1/2=3

Move +1/2 to the other side. Sign changes from +1/2 to -1/2

k/2+1/2-1/2=3-1/2

k/2=3-1/2

Find the common denominator for 3 and -1/2.

Common denominator is 2

k/2=3(2)-1/2

k/2= 6/2-1/2

k/2=5/2

Multiply k/2 with 2. Multiply 2 with 5/2

k/2 (2/1)=2(5/2)

Cross out 2 and 2. Divide by 2. Cross out 2 and 2 for 5/2(2). Divide by 2

k=5
