-4

Step-by-step explanation:

x = 1

so , 2(1) = 2* 1 - 7

= 3-7

= -4

Answer 2

$\huge{ \color{aqua}{ \underbrace{ \underline{ \color{lime}{ \mathbb{✯꧁ ⋆᭄ SoLuTiOn⋆᭄꧂✯ }}}}}}$

$\bold{ \underline{ \underline{ \red{given \ratio - }}}}$

$\mathtt{x =- 1}$

$\bold{ \underline{ \underline{ \mathfrak{ \blue{according \: to \: the \: question} }}}}$

$\mathtt{ 2x - 7}$

$\bold{ \boxed{ \mathtt{ \color{gold}{now \: on \: putting \: x = 1 \: on \: the \: equation}}}}$

$\mathtt{ = 2x - 7}$

$\tt{ = 2(-1) - 7}$

$\tt{ = -2 - 7}$

$\tt{ = -9}$
