Find the value of the expression if x=-7
LUCKY_DIMON [66]

Answer: -16

Step-by-step explanation:

49 would be the result of -7 squared. Due to the fact it is negative, it would cancel out to be positive.

For the numerator, 49-1 is equivalent to 48.

48/x+4

-7+4 = -3

48/-3

= -16

How to Simplify 6y + 5z + 8y – 3z?
Gekata [30.6K]
To simplify, you just condense all of the values with the same variable, based on the signs of those values.
In this example,
6y + 5z + 8y - 3z
is the same as 
6y + 8y + 5z - 3z
which can be simplified to 
14y + 2z
which is the answer to your question.
Hope that helped =)
