HaydenwH · Answer

do you have an equation that you could post?

Spectrum · Answer

10x +5=7

HaydenwH · Answer

first you want to get the variable on a side by itself, do you know how to do that?

Spectrum · Answer

nope.

HaydenwH · Answer

since the the variable isnt alone you have

"10x+5"=7

since 5 is being added, in order to remove it you will have to subtract 5 by both sides,

and you will be left with

10x= -2

do you know what to do from here?

Spectrum · Answer

yes, i think maybe im not sure i think multiply?

Spectrum · Answer

-20

HaydenwH · Answer

the opposite actually, you would divide both sides by 10x, which leave just the x on the left, and what number are you left with after, -2 divided by 10?

Spectrum · Answer

-5?

HaydenwH · Answer

no, that is 10 divided by -2, you are doing -2 divided by 10

HaydenwH · Answer

$$-2\div10$$

why you get on the right side -2 ? 10x +5 = 7 subtract from both sides 5 10x -5 +5 = 7 -5 10x = 2 divide both sides by 10 x = 2/10 simplifie by 2 x = 1/5
