Work Step by Step

We first use the distributive property to obtain that $k/4-.25=7$ We need to get the k alone. Thus, we cancel out the subtraction by adding .25 on both sides. This leaves us with the equation $k/4=7.25$. In order to cancel out division, we use multiplication, so we multiply both sides by 4 to get that k=29. We plug 29 in for k and confirm that our answer is, indeed, correct.
