2x-13=5
and
5x+11+4x-5=3x+24

Answer 1

1. 2x-13=5

=>2x=5+13

=>2x=18

=>x=18/2

=>x=9

2. 5x+11+4x-5=3x+24

=>9x-3x=24-6

=>6x=18

=>x= 18/6

=>x= 3

Answer 2

$Given \: simple \: equation : 2x - 13 = 5$

/* Add bothsides by 13 , we get */

$\implies 2x - 13 + 13 = 5 + 13$

$\implies 2x = 18$

/* Dividing each term by 2 , we get */

$\implies \frac{2x}{2} = \frac{18}{2}$

$\implies x = 9$

$ii) Given \: 5x+11+4x-5=3x+24$

$\implies 9x + 6 = 3x + 24$

/* Subtract bothsides by 6, we get */

$\implies 9x + 6 - 6 = 3x + 24 - 6$

$\implies 9x = 3x + 18$

/* Subtract bothsides by 3x , we get */

$\implies 9x - 3x = 3x + 18 - 3x$

$\implies 6x = 18$

/* Dividing each term by 6, we get */

$\implies \frac{6x}{6} = \frac{18}{6}$

$\implies x = 3$
