Hi, I'm currently a research student at the University of York and I've been studying computers for the last nine years.

I'm here to help the next crop of students interested in stufying computers either as a career or passion or simply to get a good grade-whatever your need,I'm ready,willing and able to provide a patient and challenging environment for you to learn in.

I have been tutoring students since sixth grade: first my younger brother, then fellow students. After my undergraduate , I spent a year in India doig pro bono tuitions for underpriviliged children in my neighbourhood.

### Make x the subject of this equation: y= 2(1-x)/(3x-1)

step 1: Open up the numerator on the R.H.S. y= (2-2x)/(3x-1) Step 2 Multiply both sides with (3x-1) y*(3x-1)=2-2x =3xy-y=2-2x Step 4 Bring -2x to the left hand side-remember to change the sign! 3xy-y+2x=2 Step 5 Bring -y to the right hand side-again, remember to change the sign! 3xy+2...

step 1:

Open up the numerator on the R.H.S.

y= (2-2x)/(3x-1)

Step 2

Multiply both sides with (3x-1)

y*(3x-1)=2-2x

=3xy-y=2-2x

Step 4

Bring -2x to the left hand side-remember to change the sign!

3xy-y+2x=2

Step 5

Bring -y to the right hand side-again, remember to change the sign!

3xy+2x=2+y

Step 6

Take x common on the R.H.S.

x(3y+2)=2+y

Step 7

Divide both sides with (3y+2)

x=(2+y)/(3y+2)

### What is an ionic substance? Are ionic substances good conductors of electricity?

Ionic compounds are compounds held together by ionic bonds. Ionic bonds are created when one element (usually a metal) loses an electron to a non metal. The element that loses electrons is called a cation and is positively charged. The element that gains electrons is called an anion and is neg...

Ionic compounds are compounds held together by ionic bonds. Ionic bonds are created when one element (usually a metal) loses an electron to a non metal. The element that loses electrons is called a cation and is positively charged. The element that gains electrons is called an anion and is negatively charged.

In the usual state, ionic substances do not conduct electricity but when dissolved or melted make good conductors. Examples: sodium chloride (NaCl)
