Question

3x+1/10=x-1/7 what is x explain how you got the answer

Answer 1

`3x+(1)/(10)=x-(1)/(7)`

To solve for 'x' we first collect simmilar terms. In this case I'll collect 'x'-terms on the left and non-'x'-terms on the right.

Start by subtracting 1/10 from both sides:

`3x+(1)/(10)-(1)/(10)=x-(1)/(7)-(1)/(10)`
and simplify:

`3x=x-(10)/(70)-(7)/(70)`

`3x=x-(17)/(70)`

We now have all non-'x'-terms on the right. We can get all the 'x' terms on the left by subtracting 'x' from both sides:


`3x-x=x-(17)/(70)-x`
and simplifying:

`2x=-(17)/(70)`

Then we can solve for x by dividing both sides by 2:

`(2x)/(2)=(-(17)/(70))/(2)`
and simplifying:

`x=-(17)/(140)`

Answer 2

3x+1/10=x-1/7 subtract 1/10 from both sides 3x=-1/7-1/10+x subtract x from both sides 2x=-1/7-1/10 add -1/7 and -1/0 1/7=10/70 1/10=7/70 -10/70-7/70=-17/70 2x=-17/70 divide by 2 ro multiply by 1/2 x=-17/140
