Solve the pair of simultaneous equations {4x + y = 5, 3x - y = 2} using i) a graph and ii) an algebraic method

a) Draw graph and find points of intersection (will be done on whiteboard). b) Sum equations to get 7x=7, so x=1 and y=1.

I keep making silly mistakes how do I stop that?


Solve the inequality: x^2 - x < 12


Solve for y: 5(y – 2) + 2(y – 3) = 19


Simplify and then solve by factorisation 3x(x+2)-7=2, to find x.
