Question

Resolva a equação:

2x-3•(x+1)/2=-1

Answer 1

Resposta:

x=1

Explicação passo-a-passo:

$2x-3\cdot \frac{\left(x+1\right)}{2}=-1\\\\\frac{x}{2}-\frac{3}{2}=-1\\\\\frac{x}{2}\cdot \:2-\frac{3}{2}\cdot \:2=-1\cdot \:2\\\\x-3=-2\\\\x-3+3=-2+3\\\\x=1$

Answer 2

Resposta:

x=1

Explicação passo-a-passo:

2x-3(x+1)/2= -1

4x-3(x+1)= -1x2

4x-3(x+1)= -2

4x -3x-3= -2

4x-3x= -2 +3

x= 1
