Linear- A linear equation has a value which is un known. For example, 7x-3=6When working out Linear questions you can use the trial and improvement method. Think what would times by 7 but not me to big so you can take three and end with 6. e.g x=2 7x2-3=11 too big. x=1 7x1-3=4 too low. And you would carry on from there.
equations with brackets-2(3x-5)=4x
firstly times the number out of the barckets with the ones in them.
6x-10=4x after this subtract 4x from both sides.
2x-10=0 Then add ten to each side.
2x=10 finally divide by 2.
x=5
