For all straight line equations as the one above, the equation is y=mx+c where: m is the gradient, c is the y-intercept. Thus from the arrangement of the given equation, gradient ...
a + 3b = 12, a = 12 - 3b
3(12-3b) + b = 20
36-9b + b = 20
36-8b = 20
8b = 16
b = 2
2a + 12 = 24
2a = 12
a = 6
x^2 - 8x - 20
(x - 10)(x+2)
(Explanation and helping understanding) Remember the last 2 numbers must multiply to equal the last number in the question and add together to equal the middle nu...
