SOLUTION: 0=5(k+9)

Question 72928: 0=5(k+9)

Given:
.
0=5(k+9)
.
First do the distributive multiplication on the right side to get:
.
0 = 5*k + 5*9 = 5x + 45
.
Then subtract 45 to eliminate the 45 on the right side. The result of this subtraction
is:
.
-45 = 5k
.
Finally transpose sides and then divide both sides by 5 to solve for k. The answer is:
.

.
which reduces to:
.

.
You might have been able to spot the solution earlier too. For the given equation to
be true, 5 has to be multiplied by zero to equal zero. Therefore you can say that
the quantity (k + 9) has to equal zero and this means that k has to equal -9.
.

Hope this helps you to understand the method of solving algebraic equations such as this one.
