Question

How to solve for x:
(2x+18)/6=(2x+16)/2

Answer 1

x = -15/2

Answer 2

\[\frac{a}{b}=\frac{c}{d}\]

becomes:

\[\frac{d}{b}=\frac{c}{a}\]

Does this help?

Answer 3

Not really, the answer book says that you need to multiply the 2x+16 by 3 so:
3(2x+16)

Answer 4

Yes, you could do that, so you need to multiply both sides by six.

(2x+18)/6*6=(2x+16)/2*6
2x+18=3(2x+16)

Does this help you solve for x?

Answer 5

Oh I think because u multiply both sides by 6 so 1/6 X 6=1 and 1/2 x 6 =3

Answer 6

Yes! Correct.

Answer 7

Yea

Answer 8

Okay thanks alot.What I did wrong was doing 6(2x+18) and 6(2x+16)

Answer 9

Don't forget you need to still divide the equation by 6 and 2 respectively, so:

6(2x+18)/6 and 6(2x+16)/2

Answer 10

Oh now It's clear

Answer 11

\[\frac{ 1 }{ 6 }(2x+18)=\frac{ 1 }{ 2 }(2x+16)\]

Answer 12

\[x=\frac{ -15 }{ 2 }\]
