Answer 1

$\LARGE{ \underline{\underline{ \pink{ \bf{ANSWER}}}}}$

x = 11/7

Step-by-step explanation:

• 7x - 2 = 9 [Bringing numerical terms to right side]

• ◇Note◇
• If we are bringing any term to LHS or RHS its sign will change...If it is '-' in LHS and when we bring it to right side it will change ti '+' ...

• 7x = 9 + 2

• 7x = 11

• x = 11/7

$\implies$Solution:-

$7x - 2 = 9$

$7 \times = 9 + 2$

$\implies$$( - 2 \: will \: become \: + 2 \: when \: it \: will \: go \: on \: the \: other \: hand.)$

$7x = 11$

$x = \frac{11}{7}$

$\implies$Solving by putting the value:-

$7 \times \frac{11}{7} - 2 = 9$

${\not{7}} \times \frac{11}{ \not{7}} - 2 = 9$

$11 - 2 = 9$

$11 = 9 + 2$

$11 = 11$

$= 11 - 11$

$= 0$
