Question

Is 7 a solution to -7(x+5)=-14

Answer 1

no

Explanation:

Answer 2

`\qquad\qquad\huge\underline{\boxed{\sf Answer}}`

Let's plug in the value of x as 7, to check if 7 is the solution to given equation ~

`\qquad \sf  \dashrightarrow \: - 7(x + 5) = - 14`

`\qquad \sf  \dashrightarrow \: - 7(7 + 5) = - 14`

`\qquad \sf  \dashrightarrow \: - 7(12) = - 14`

`\qquad \sf  \dashrightarrow \: - 84 \: \cancel= - 14`

Since, the terms on both sides aren't equal. therefore we can say that 7 isn't the solution ~
