Step 1: Rearrange one equation to make y the subject. In equation B, we can move the 3x to the other side, making it negative and making the equation y=23-3xStep 2: Substitute our new value for y into equ...
The aim here is to find the probability that the football match is cancelled in both the case that it rains and in the case that it doesn't. This helps to break the question down; we can find the probabil...
Step 1. Pick one of the equations and move all of the x values to one side of the equal and move all others to the other side e.g X = 2y + 3Step 2. Make sure the X value is not times by a number e.g 2...
First you need to remember the equation area of a circle = πr2 with r being the radius. Therefore as we are given the area of the cicle we need to rearrange the equation to give us the radius. ...
First gather all x terms on left hand side,7x2-13x-2=0.Since 7 is a prime number we can begin factorisation,(7x+/-?)(x+/-?)=0.We know there must be a +/-2 and +/-1 in place of the q...
