Question

Solve the equation : 3 by 2 x + 4 = 1 by 3

Answer 1

$\frac{3}{2x + 4} = \frac{1}{3} \\ 9 = 2x + 4 \\ 5 = 2x \\ x = \frac{5}{2}$

Answer 2

Welcome to the concept of linear equation, which is a part of algebra!

This is a question based on the concept of linear equation in one variable.

Here, we use variables and constants and the method of transposition to solve questions.

$= > \frac{3}{2x + 4} = \frac{1}{3}$

Do cross multiplication.

$= > 3 \times 3 = 1(2x + 4)$

$= > 9 = 2x + 4$

$= > 9 - 4 = 2x$

$= > 5 = 2x$

$= > \frac{5}{2} = x$

Verification:-

LHS=3/2x+4. RHS=1/3

3/2×5/2+4

3/5+4

3/9

1/3=1/3

So, LHS=RHS, hence verified and it is correct
