You could solve this equation by using substitution, since both equations are in a' y = ' form. You can substitute the first equation into the first, as they both equal y, they both equal each other : x+1...

L1: y=3x-2L2: 3y-9x+5=0 3y=9x-5 y=3x-5/3standard form of a linear line, y=mx+c where m is the gradient. Gradient in both equations is 3 therefore they are parallel

First, multiply out the bracket on the left hand side. Then move the numbers (without "x's") to the right hand side. After that, move all the x values to the left hand side. Finally, divide both...

2(2x-4)>28In this question we want the get the x on it's own so we need to remove everything beside it.So we multiply out the brackets 2(2x-4) = 4x-8So then we have 4x-8>28.Then we move the 8 to the...

Before we start any integration steps it would be wise to try and simplify the fraction that we have been given. We want to get rid of that denominator so we will start by expanding out the numerator. Thi...
