Question

Of the following options, what could be a possible first step in solving the equation −7x − 5 = x + 3?

adding 7x to both sides of the equation
subtracting 5 from both sides of the equation
adding x to both sides of the equation
combining like terms, -7x+x=-6x

Answer 1

which one of those would eliminate the term in x on one side of the equation?

Answer 2

adding x to both sides?

Answer 3

No
that would not do it
left side term would change to -6x and right side would become 2x

Answer 4

suppose we had -x on the left
what would happen if we added x to it?

Answer 5

it would be a positive

Answer 6

-x + x = what?

Answer 7

a positive x

Answer 8

no
-x + x = 0

Answer 9

to solving that equation you have to move the x to one side, when you move the x you have to change the sign and add to the other x. lets move the right x to the left side
−7x − 5 = x + 3
-8x=8
when you move the x to the left its a -x when u add its a -8x
and the same with the 5
after that you have to leave the x alone so you have to divide the -8 to the 8 like this 8/-8 and the answer is -1

Answer 10

idk :(

Answer 11

in the question we have -7x on left side
so in order to get rid of this what do we add?

Answer 12

we add it to both sides

Answer 13

yes we add it to both sides but what do we add
-7x + something must = zero

Answer 14

-7x and -7x cancel each other out

Answer 15

right!!
