-3/5+5x/4=2x+1/2

Answer 1

Resposta:

Explicação passo-a-passo:

-3/5+ 5x/4= 2x+1/2

-12+25x= 40x+10

------------------------

         20

corta o 20

-12+25x= 40x+10

25x- 40x= 10+12

-15x= 32

x= -32/15

Answer 2

Resposta:

Explicação passo-a-passo:

$-\dfrac{3}{5} +\dfrac{5x}{4} =2x+\dfrac{1}{2} \\\\\\-\dfrac{-12}{20} +\dfrac{25}{20} =\dfrac{40x}{20} +\dfrac{10}{20} \\\\\\-12 + 25 = 40x + 10\\40x - 25 = - 12 - 10\\15x = - 22\\\\x = \dfrac{-22}{15}$
