Question

4+4g+c=0
1+2f+c=0
39+8g+10f+c=0 solve these equation​

Answer 1

Step-by-step explanation:

1. 4+4g=-c_____(1)

• 1+2f=-c______(2)
• RHS is equal therefore LHS is also equal
• 4+ 4g = 1+ 2f =-c
• 4-1 + 4g - 2f =-c
• 4g - 2f +3 =-c____(3)

2. 39+8g+10f+c=0

• 39+8g+10f= -c_____(4)
• put eq (3) in eq (4)
• 39+8g+10f=4g-2f+3
• 39-3+8g-4g+10f+2f=0
