Question

2/7x = 10 (explain if possible)

Answer 1

You need to isolate the variable (7x) first

Answer 2

ok how do I do that since its attached to the 2 as well?

Answer 3

What happens if you multiply each side of the equation by 1/2.

Answer 4

so I multiple 2/7 by 10/1?

Answer 5

Sorry connection issues...What is 2/7x times 1/2?

Answer 6

where are you getting 1/2 from???

Answer 7

Try moving the 7x to the right hand side of the equation.

Answer 8

\(2 = (7x)(10)\)

Answer 9

Can you solve for x now?

Answer 10

Forget everything I said ..easy way to solve. Multiply both sides by 7/2.

Answer 11

so if I minus 10 I would then end up with
-8 = 7x now if I divide I get a decimial and that's def wrong?

Answer 12

You can't minus here. @c1282

Answer 13

You have to do multiplication.

Answer 14

so then how are we isolating x?the answer cant b -8= 7x

Answer 15

The 10 and the 7x.

Answer 16

m not trying to get the answer but I do not understand with 10 and 7x what im suppose to do can u pls try breaking it down even if u use different numbers

Answer 17

nevermind ill see if I find another way thank u

Answer 18

Okay.
\(\dfrac{2}{7x} = 10\)
We want to solve for x- we don't want to leave it in a fraction form.
Now 10 is on the other side of the = sign.
Here we can use 'cross multiplication' between the 7x and 10.
So we can move the 7x to the right hand side, but its multiplied with the 10.
\(2 = (10)(7x)\)
Are you getting it so far?

Answer 19

\[\frac{ 2 }{ 7x } x \frac{ 7 }{ 2 } = x\]

Answer 20

Now do the same for the other side of the equation\[10 x \frac{ 7 }{ 2}\]
