Question

Solve -2(8n - 3) = 43(n + 7). write the solution as an integer or decimal. Show your work (simply).

n = __​

Answer 1

n=7.14

Explanation:

-2(8n-3)=43(n+7)

distribute

-16n+6=43n+301

add 16n on both sides

6=43n-301

add 301 on both sides

307=43n

divide both sides by 43

n=7.1395

Answer 2

n = - 5

Explanation:

- 2(8n - 3) = 43(n + 7) ← distribute parenthesis on both sides

- 16n + 6 = 43n + 301 ( subtract 43n from both sides )

- 59n + 6 = 301 ( subtract 6 from both sides )

- 59n = 295 ( divide both sides by - 59 )

n = - 5
