1. –3g + 2
2. –4λ – 4
Step-by-step explanation:
1. Given data: –7g and 4g + 2
Now, let us find the sum of –7g and 4g + 2.
Sum of –7g and 4g + 2 = (–7g) + (4g + 2)
= –7g + 4g + 2
= –3g + 2
2. Given data: 6λ and 2λ – 4
Now, let us find the difference when 6λ is subtracted from 2λ – 4.
6λ subtracted from (2λ – 4) = (2λ – 4) – 6λ
= 2λ – 4 – 6λ
= –4λ – 4
Hence the sum of –7g and 4g + 2 is –3g + 2 and the difference when 6λ is subtracted from 2λ – 4 is –4λ – 4.
