<span>9 (p − 4) = 18
9p - 36 = 18
9p = 18 + 36
9p = 54
p = 54/9
p = 6</span>
Answer: x = 0
Step-by-step explanation: To solve for <em>x</em> in this equation, our first step is to simplify the left side by distributing the 10 through both terms inside the parentheses.
When we do that, we get 10 times x which is 10x
and 10 times -2 which is -20.
So we have 10x - 20 = -20.
Adding 20 to both sides, we get 10x = 0.
Divide both sides by 10 and <em>x = 0</em>.
