Woah huge help dude thanks, but what happens to the 5 in the red/second question? I swear my teacher said we couldn't just make the number disappear when we are factoring it.
In the red question I did not factor, I divided through by 5 ... I could do this because it was an equation and I could do 0 divide by 5 still equals 0 ... You MUST have an equation to divide through so you CANNOT do this with the green question as there is no equation ... Hence the need to factorise instead
2. Hey mate had a go at a bunch of simultaneous equations and this is the only one where I have to idea how to get the correct answer
