5k-7=-7 solve the equation to what is k

2 answers:

5 0

So 5k-7=-7
You need to do the opposite of addition,which is subtraction so...
5k-7=-7
+7
__
K=0
and to double check it,replace the (or variable) with our answer (0)...
so
5×0-7=-7
solve the problem...and
-7=-7√

First you should add +7 on both sides of the equation so you will have:
5k = -7 +7 ⇒ 5k = 0 so k = 0 :)))
i hope this is helpful
have a nice day

If 3x+54+(65 × 32)+ 902- (43/12) =y, then what is y?

IceJOKER [234]

Answer:

We cannot solve without a value for x. The simplified form is $3x+\frac{36,389}{12} =y$

Step-by-step explanation:

If the equation is $3x+54+(65)(32)+902-\frac{43}{12}=y$ then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

$3x+54+(65)(32)+902-\frac{43}{12}=y \\3x+54+2,080+902-\frac{43}{12}=y \\3x+3,036-\frac{43}{12}=y \\3x+\frac{36,432}{12} -\frac{43}{12} =y\\3x+\frac{36,389}{12} =y$
