Solved by forming a simultaneous equation and eliminating y in order to find the values of x and y.

x=7
-3x + 5 = 20 -3x = 15 x = -5
x = -8
7x = 3x - 12 4x=-12 x=-3

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 6
x = 5, y = -1
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
