Question

solve the question
4x+9=7x+16
plz ​

Answer 1

Step-by-step explanation:

4x-7x+9=16

-3x+9=16

-3x=16-9

-3x=7

x=-7/3

Answer 2

Answer :-

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

__________________________

To Find :-

The Value of X.

__________________________

Equation :-

$4x + 9 = 7x + 16$

__________________________

Step By Step Solution :-

To Find the value of X. We have to solve the Equation. So Let's Do it !!

$= > 4x + 9 = 7x + 16 \\ \\ = > 4x - 7x = 16 - 9 \\ \\ = > - 3x = 7 \\ \\ = > x = \frac{ - 7}{3}$

Therefore the value of X = $\frac{ - 7}{3}$

__________________________

Verification :-

$= > 4x + 9 = 7x + 16$

By putting the value of X.

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

L. H. S.

$= > 4 \times \frac{ - 7}{3} + 9 \\ \\ = > \frac{ - 28}{3} + 9 \\ \\ = > \frac{ - 28+ 9 \times 3}{3} \\ \\ = > \frac{ - 28 + 27}{3} \\ \\ = > \frac{ - 1}{3}$

R. H. S.

$= > 7 \times \frac{ - 7}{3} + 16 \\ \\ = > \frac{ - 49}{3} + 16 \\ \\ = > \frac{ - 49+ 16 \times 3}{3} \\ \\ = > \frac{ - 49+ 48}{3} \\ \\ = > \frac{ -1}{3}$

Therefore L. H. S. = R. H. S.
