What is the answer to the equation -2x-8=-10

Oxana [17]

You need to get "x" by itself on one side

$-2x-8=-10$

Add positive eight on both sides---because its the opposite of negaitve

$-2x-8+8=-10+8$

$-2x=-2$

Divide -2 by -2

-2÷-2=1

<u> $x=1$ </u>

What does x equal? 5x = 2/7 ; x =

Pavlova-9 [17]

Answer:

it would be x=17 1/2

Step-by-step explanation:

i am going to go a little more into detail.

you would first have to divide each side to isolate the variable

x=5/2/7

simplifying steps:

you would have to change the 5 into 5/1

5/1÷2/7

now you have to keep the first number, change the sign, and then flip the last number, AKA KCF

5/1*7/2

35/2

and you can simplify this into a mixed number

17 1/2

hope this helps! have a nice day :)
