y =x/3 - 2a
y + 2a = x/3
3y+6a = x

Increase the power by one and divide by the new powere.g. integrate x²+5x + 3Answer: x³/3 + 5x²/2 + 3x

The best way to solve simultaneous equations is by substitution. The first step is to pick a variable to eliminate. In this case, I'm going to choose to eliminate y because the first equation has a y on i...

Sin, cos and tan are functions that help you work out either, the missing angle or one of the missing lengths of a side in a right angle triangle.To work out the missing angle you need two side lengths, d...

b = (2a + 5)/3 Step 1 - Multiply both sides by 33b = 2a + 5Step 2 - subtract 53b - 5 = 2aStep 3 - divide by 2(3b - 5)/2 = a
