Question

What is the value of x?

-2/7x +6 +1/7x =18

Answer 1

is this your equation?
\[-\frac{ 2 }{ 7 }x +6 +\frac{ 1 }{ 7 }x=18\]

Answer 2

Yes

Answer 3

Ok! Now, please multiply by 7 both sides of your equation, then write what you get

Answer 4

-2/7x +6x = 126

Answer 5

I think not, because you have to performthe subsequent calculus:
\[7*(-\frac{ 2 }{ 7 }x+6+\frac{ 1 }{ 7 }x)=7*18\]

Answer 6

for example:
\[7*(-\frac{ 2 }{ 7 }x)=-2x\]
now try, pleae

Answer 7

Do you have to divide both sides by 7?

Answer 8

No, I have to multiply both sides by 7, as I wrote above

Answer 9

Okay, so it's -2/7x = -14x @Michele_Laino

Answer 10

\[-2*x+42+x=126\]
is what you get after multiplication by 7
