Answer:
STEP n1:
Equation at the end of step 1
(g•(5c+4))-((((5c+4)2)+8•(5c+4))-2) = 0
STEP 2:
Equation at the end of step 2
g • (5c + 4) - (25c2 + 80c + 46) = 0
STEP 3:
Equation at the end of step 3
5gc + 4g - 25c2 - 80c - 46 = 0
STEP 4:
Solving a Single Variable Equation
4.1 Solve 5gc+4g-25c2-80c-46 = 0
