To solve these equations we must make them equal to eachother. This gives us x²+4x+6=x+4, we must then subtract the 'x+4' fro...

We know that Amy bought 7 tickets for £24.50. This means to find out the price for each ticket, we divide the price for 7 tickets by 7: price per ticket = (24.50/7) = £3.50 Now we can find the total numbe...

To answer this question we need to combine like terms so that we do not have multiple x's. Knowing the order of operations is key here. First, we must multiple the coefficients outside the parentheses wit...

I would start off by asking them if they know the Pythagoras theorem. If they don't, I would refresh their memory and explain that its a²+b²=c² where...

Start by multiplying equation (2) by 4 so both equations contain 4 lots of x: 4x - 12y = 20 Then take away equation 1 from equation 2 to eliminate x -13y = 13 divide by 13 and then reverse the negative si...
