Answer 2

@iambatman Can you please help me?

Answer 3

The first step is to turn the sentence, into a mathematical equation

Answer 4

I did

Answer 5

can i see it?

Answer 6

4x+3=6x-5

Answer 7

@UnkleRhaukus

Answer 8

that is right , (good work)

now we just have to solve this equation for the unknown number (x)

Answer 9

That's were I'm stuck

Answer 10

add 5 to both sides of the equation,

Answer 11

4X+8=6X

Answer 12

I added 4x and 6x

Answer 13

when I tried to solve it

Answer 14

4x+3 = 6x - 5
4x+8 = 6x

good,
now take-away 4x form both sides

Answer 15

*from

Answer 16

2x

Answer 17

8=2x

Answer 18

that is right,
now just divide both sides by 2

Answer 19

4!

Answer 20

yessss \[\checkmark\]

Answer 21

OMG thank you so much

Answer 22

Wait I have a question why couldnt I add -5

Answer 23

Isn't it -5?

Answer 24

@UnkleRhaukus

Answer 25

4x + 3 = 6x - 5

if we added -5, (instead of adding 5)
this would have become

4x + 3 - 5 = 6x - 5 - 5
4x - 2 = 6x - 10

but this operation hasn't made the equation any simpler

Answer 26

Oh okay...but when - is in front of a number doesn't that mean it becomes a negative? @UnkleRhaukus

Answer 27

well -5, is negative five, to get rid of this term from the equation, we have to apply the inverse operation to both sides (i.e. +5), this will cancel the -5 away
