Answer:
-2x +4 = 20
Step-by-step explanation:
given

by making x the subject, you need to subtract 4 from 20
thus


and also you need to divide through by -2


A=48
b=144
c=-84
First, you simplify the second equation by multiplying 6 to 2x and 6 to 7. Then, you get the two equations, (4x-2) times (12x+42). You then use the FOIL method, multiplying 4x to 12x, 4x to 42, -2 to 12x, then -2 to 42. Simplify. Then number before x squared is your a value, value before x is b, and the value without x is c.
