Question

x/5 + 1 = 2x/3

x/2 + x/3 = 1

ajuda pfvr

Answer 1

Olá!!!

Resolução!!!

x/5 + 1 = 2x/3

mmc ( 5, 3 ) = 15

3x/15 + 15/15 = 10x/15

3x + 15 = 10x

3x - 10x = - 15

- 7x = - 15 • ( - 1 )

7x = 15

x = 15/7

S = { 15/7 }

x /2 + x/3 = 1

MMC ( 2, 3 ) = 6

3x/6 + 2x/6 = 6/6

3x + 2x = 6

5x = 6

x = 6/5

S = { 6/5 }

Espero ter ajudado!!!

Answer 2

$\frac{x}{5} + 1 = \frac{2x}{3} \\ \\ \frac{3x + 15 = 10x}{15} \\ \\ 10x - 3x = 15 \\ 7x = 15 \\ x = \frac{15}{7}$
------------------------------------
$\frac{x}{2} + \frac{x}{3} = 1 \\ \\ \frac{3x + 2x = 6}{6} \\ \\ 5x = 6 \\ x = \frac{6}{5}$
