Question

(working with absolute value). Solve.
I3x+4I=Ix-7I

Answer 1

if |a| = b
then a= b or a=-b

so, for
|3x+4| = |x-7|
you get,
|3x+4| = x-7 or |3x+4| = -(x-7)
which in turn , you get
3x+4 = x-7 or 3x+4 = -(x-7)

Answer 2

can you solve those 2 equations to get x ?

Answer 3

the first one is 11/-2 = x and the second one is 3/4=x

Answer 4

@hartnn

Answer 5

ok, x =- 11/2 and x= 3/4 are correct! good :)

Answer 6

is that it?

Answer 7

yes, thats it :) quite simple, right ;)

Answer 8

yah, is that how all of those problems work?

Answer 9

for = sign in between, all of the problems use

if |a| = b
then a= b or a=-b

and work same way :)
