If you want to calculate 5*(a-4) - 8*a = 55, you have to do few steps to get to know the value of the a.

5*a - 20 - 8*a = 55
-3*a = 55 + 20
-3*a = 75   /(-3)
a = - 25

The correct result and the value of the a is -25.

Using differentiation from first principles, prove that the gradient of the line y=mx + c is m
adell [148]

\frac{dy}{dx}  = m
because when you differentiate, only the constant of the x remains (which is m in this case), and c being another constant independent of x, is 0 when differentiated. hence, since dy/dx is the gradient of the line, m is therefore the gradient
