Question

Solve 1/4 (k-1) =7

Answer 1

SO start by the opposite of multiplying which is division with the 1/4

Answer 2

What you do to one side you do to the other, but the opposite

Answer 3

So instead of multiplying by 1/4 we multiply 7 by 4 and get 28

Answer 4

\[\frac{1}{4}(k-1)=7\]Multiply both sides by 4.\[k-1=28\]Add 1 to both sides.\[k=29\]

Answer 5

So (k-1)=28

Answer 6

Now add the one to both sides and get k=29
