Question

5n-14(10+8n)=-19+14n

Answer 1

`5n - 14(10 + 8n) = - 19 + 14n`

`5n - 140 - 112n = - 19 + 14n`

`- 140 - 107n = - 19 + 14n`

`- 140 + 19 = 14n + 107n`

`- 121 = 121n`

`- ( 121)/(121) = n`

`- 1 = n`

Answer 2

n=-1

Explanation:

5n-14(10+8n)=-19+14n

-107n-140=-19+14n

+140 +140

-107n=14n+121

-14 -14

-121n=121

/-121 /-121

n=-1
