Firstly, before we even approach the bracket containing the x term, we want to deal with the fraction. The first step should be multiplying by 4 to cancel out the denominator on the right. This leaves us ...

15x^2 − 4x + x^2 + 9x − x − 6x^2 = ?First you can break up the question and sort out the x^2 part of the equation to make it easier: 15x^2 + x^2 − 6x^2 = 10x^2Then you are left with solving the second p...

Use the FOIL method:F - FIRST: the first term in either bracket, multiply: 2x(9x) = 18x². O - OUTSIDE: the terms further from the centre of the brackets, multiply: 2x(-2) = -4x. I - INSIDE: the...

Before starting, look whether either equation has common factors. Equation 1 does common factor 2, so divide it by 2 both sides to get 1) 2x - y = 14. Rearrange 1) to get one unknown in terms of the other...

1+4+5=10. 40/10 = 4. 1 x 4= 4 = 4 sweets for Tommy. 4 x 4 = 16 sweets for Anna. 5 x 4 = 20 sweets for Jacob
