Make y the subject of equation 1:y = 2x - 1Substitute this value of y into equation 2:3x + (2x - 1) = 14Simplify:5x - 1 = 14Solve for x:x = 3Substitute this value of x into original equation:2(3) - y = 1S...

x=1y=2
x= -29/11y=2/11

v² = u² + 2as. The question is asking us to make s the subject of the formula and so we must find the equation equal to s. The golden rule of the rearranging topic is whatever you do...

The point at which the explanation of the solution is started, will depend on the level of understanding of the student and previous knowledge on the subjectA root is a numerical value that repre...

The key to this is to not expand everything out and try work it out through that process. The easiest way is to notice that (x^2+5x+6) = (x+2), (2x^2+10x+12)=2(x+3)(x+2) and (x^2+x-2)= (x+2)(x-1).From thi...
