Question

how do i solve for x in the following, 7x-5+2x=3-4x+12

Answer 1

move all the x terms to one side .. to the left side for example
you do this by adding 4x to both sides of the equation
what will you get ?

Answer 2

9x-5=-4x+15?

Answer 3

no
7x-5+2x=3-4x+12 adding 4x to both sides ->
7x +2x+4x -5 = 3+12-4x+4x
13x-5=15

Answer 4

all the terms of x.
9x+4x=20

Answer 5

13x=20
x=20/13

Answer 6

nok thank you. i had that all messed up

Answer 7

now we need to move this '5' to the right side since we want all the x terms at the left sides
.. we do this by adding 5 to both sides of the equation
what we get?

Answer 8

@miteshchvm we better let people try and learn then solve for them ..

Answer 9

than*

Answer 10

ya dude @Coolsector ;) sure

Answer 11

take the variables at one side & constants at one side as\[7x+2x+4x=3+12+5 .........(By \space Transposition )\]\[13x=20\]by dividing 13 both sides.we have\[\frac{13x}{13}=\frac{20}{13} \implies x=\frac{20}{13}\]
