Step-by-step explanation:
Answer:
-128
Step-by-step explanation:
When it says that x = a number, it means you just need to plug in that number for x in the equation. So in this case, we'd plug in -12 and get:
y = -200-6(-12)
Simplify. According to PEMDAS, we do multiplication first. If a number is in parentheses, you multiply it by the number in front of (to the left) of it. In this case, we multiply -6 x -12 and get:
y= -200+72
Add, and our final answer is:
y=-128
Hopefully this helped, and if I was correct, I'd appreciate it if you marked me as the Brainliest :)
Answer:
- distributive property
- combine like terms
- division property of order
Step-by-step explanation:
At the second step, parentheses have been eliminated. The <em>distributive property</em> is used for that.
At the third step, -25-14 is replaced by -39. This process is called <em>combine like terms</em>.
At the last step, the inequality is divided by the coefficient of x. The division is by a negative number, so the order symbol is reversed, according to the <em>division property of order</em>.
