Question

2x/3+1/2=x14-3/2
Me ajudar

Answer 1

Resposta:

S = {3/20}

Explicação passo-a-passo:

$\frac{2x}{3} + \frac{1}{2} = 14x - \frac{3}{2} \\ \frac{4x + 3}{6} = \frac{84x - 9}{6} \\ 4x + 3 = 84x - 9 \\ 4x - 84x = - 9 - 3 \\ - 80x = - 12 \\ 80x = 12 \\ x = \frac{12}{80} \\ x = \frac{12 \div 4}{80 \div 4} \\ x = \frac{3}{20}$

Answer 2

se for:

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

mmc(2,3,4) = 12

reescreve:

8x + 6 = 3x - 18

8x - 3x = -18 - 6

5x = -24

x = -24/5
