Question

Solve or find a in the equation

Answer 1

`{\qquad\qquad\huge\rm\underline{\underline{\Répondre}}}`

`\qquad \rm\dashrightarrow \:3a + 1 > ( - 7a - 14)/( - 4)`

`\qquad \rm\dashrightarrow \:3a + 1 > ( -( 7a + 14))/( - 4)`

`\qquad \rm\dashrightarrow \:3a + 1 > ( 7a + 14)/( 4)`

`\qquad \rm\dashrightarrow \:4(3a + 1) > 7a + 14`

`\qquad \rm\dashrightarrow \:12a + 4 > 7a + 14`

`\qquad \rm\dashrightarrow \:12a - 7a > 14 - 4`

`\qquad \rm\dashrightarrow \:5a > 10`

`\qquad \rm\dashrightarrow \:a > (10)/(2)`

`\qquad \rm\dashrightarrow \:a > 2`

Therefore, the correct choice is D
