Question

Solve the equation for k.
4k - 2z = 8

Answer 1

k = 2 + (1/2)z

Explanation:

1) Isolate 4k by adding 2z to both sides: 4k = 8 + 2z

2) Divide all three terms by 4: k = 2 + (1/2)z

Answer 2

4k-2z=8

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

4k-2z+2z= 8+2z

4k= 8+2z

Divide by 4 for 4k and 8+2z

4k/4= 8/4+ 2z/4

k= 2 +1/2z

Answer: k= 2 +1/2z
