First we must multiply the coefficient of x2 by the value with no x associated with it3x3 = 9Now we must find two numbers that add to make 6 and multiply to make 9+6x9 3 and 3Now we need to split the coef...

Rewrite the equation for L2 to find an equation for y4y=12x-16; y = 3x - 4 2. The x-coefficient gives the gradient (or slope) of the line, so since the gradient of L1 is 3, and as we have just shown, the ...

1^st consider the bonding in methane, CH4. The carbon atom forms 4 single covalent bonds to hydrogen atoms. However, when we consider the electronic configuration of Carbon (electrons-in-box not...

The first step is to create a basic checklist which can be used for any of these types of questions. This could include a few grammar tenses and structures, a few versatile bits of vocabulary, and some po...

3x+3y=5      6x+5y=9Multiply the first equation by 2 to get a workable x coefficient:6x+6y=10Write the equations above each other and subtract them:6x+6y=10                                                ...
