example: solve the simultaneous equations 3x+2y=4 and 2x+y=3

1:   3x+2y=4
2:   2x+y=3

want to either get same number of x's or same number of y's in equa...

1. Convert the hexidecimal number D6 to decimal Since it is base-16, we multiply the first digit (6) by 16^0 - giving us 6 We then multiple the second digit (D - which equates to 13) by 1...

We all make silly mistakes when in comes to Maths, so here are some common mistakes to help you out. 1. Partial Fractions: Many students think x+2/(x+1)^2 becomes A/(x+1) + B/(x+1) This ...

This is a good question and it refers to the difference between deflation and disinflation. Sometimes if inflation is at 2% and it decreases to 1.5% for example, there will still continue to be a general ...

(2x+3) (2x+1) = 4x^2 + 8x + 3

(2x-8) (x-4) = 2x^2 - 16x - 32

(4x^2+8x+3) - (2x^2-16x-32) = 1

2x^2 - 8x - 29 = 1

2x^2 - 8x - 30 = 0

x^2 - 4x - 15 = 0

Using the qua...
