Question

13. 8 (x - 3) - (6 - 2x) = 2 (x + 2) - 5 (5 - x)
14. 3 (n - 4) + 2 (4n – 5) = 5 (n + 2) + 16​

Answer 1

Answer:

Given, 3(n−4)+2(4n−5)=5(n+2)+16

⟹ 3n−12+8n−10=5n+10+16 ...[By Distribution Law]

⟹ 11n−22=5n+26 ...[On simplifying]

⟹ 11n−5n=22+26 ...[Transposing x terms to one side]

⟹ 6n=48

⟹ n=

6

48

⟹ n=8.

Answer 2

Step-by-step explanation:

13) 8x-24-6+2x=2x+4-25+5x

10x-30=8x-21

10x-30-8x+21=0

10x-8x-9=0

2x=9

x=9/2

14)3n-12+8n-10=5n+10+16

11n-22=5n+26

11n-22-5n-26=0

6n-48=0

6n=48

n=48/6

n=8
