Question

Me ajudem por favor

3(x+2)/5+3(x+1)/4=2

Answer 1

Olá!

É fácil! Veja:

3(x + 2) ÷ 5 + 3(x + 1) ÷ 4 = 2

$\frac{3x+6}{5}$ + $\frac{3x + 3}{4}$ = 2

$\frac{3x+6}{5}$ + $\frac{3x + 3}{4}$ -2 = 0

$\frac{12x+24}{20}$ + $\frac{15x + 15}{20}$ - $\frac{40}{20}$= 0

12x + 24 + 15x + 15 - 40 = 0

12x + 15x + 24 + 15 - 40 = 0

27x - 1 = 0

27x = 1

x = $\frac{1}{27}$

Abraços!
