$\huge\bold{{\red{A}}{\blue{N}}{\red{S}}{\blue{W}}{\red{E}}{\blue{R}}{\red{❥}}}$

6

$\small\mathfrak{SoLuTiOn}$

$\small\bold\green{Step \ 1:}$

$= > \frac{x}{3} + 5 = 7$

$\small\bold\blue{Step \ 2}$

$= > \frac{x}{3} =7 - 5$

$\small\bold\red{Step \ 3}$

$= > \frac{x}{3} = 2$

$\small\bold{Step \ 4}$

$= > x = 2 \times 3$

$\small\bold\purple{final \ answer}$

$= > x = 6$

$\small\mathfrak\red{Explanation}$

First 5 will move to R.H.S. as it has a conferned sign infront if it.

Ehen it moves to R.H.S. it get subtracted as in L.S.H. it was added.

Now after subtraction it gives 2 as its difference.

Now the constant 3 moves to R.H.S. being multilied by 2.

On multiplication it gives 6 as its product.

Hence 6 is the value of x

Points to remember:-

• Any equation contains two sides :-
• L.H.S. (Left hand side) & R.H.S. (Right hand side)
• The L.H.S. part contains veriables and RHS contains constants.
• Where if there is a constant on LHS it has to be shifted to RHS with a change in the sign.
• The rule is for veriables too.

• If it has plus (+) sign it whould change to minus(-).
• If it has minus it eould change to plus.
• If there is a division sign it will be multiplication.
• And if it had a multiplication sign it would be division.

1) what are veriables?

=>All characters from A to Z are called veriables.

2)What are constants?

=>All numbers from 0 to infinity are constants.

Hope it helped u buddy..

Thank you....☺❤
