The first step would be to have the x's on their own so add three to both sides so the equation goes from y=7x-3 to y+3=7x. The current subject is 7x= we need x= so both sides need to be divided by 7. Thi...

First we should be aware of the relationship bewteen the denominator of the two fractions. Since x^2-9=(x+3)(x-3), we can multiply (x-3) on both numerator and denominator of the fraction of 2/(x+3). Henc...

Answer: -3n + 2Explanation: 'n' stands for term number. The 'nth' term is a formula with 'n' in it which enables you to find any term of a sequence. This sequence of numbers changes by the same a...

To find the answer first you have to take a log of both sides.

I am going to use log to the base 2 for my example - but any base will work as long as they are the same on both sides of the equals s...
