Question

2x + 3= x+1




-3x +5=7



2x +5x =12



3x/2=8



6x/4=8​

Answer 1

Respuesta:

$2x + 3 = x + 1 \\ 2x - x = 1 - 3 \\ x = - 2$

$- 3x + 5 = 7 \\ 5 - 7 = 3x \\ - 2 = 3x \\ - \frac{2}{3} = x$

$2x + 5x = 12 \\ 7x = 12 \\ x = \frac{12}{7}$

$\frac{3x}{2} = 8 \\ 2 \times \frac{3x}{2} = 2 \times 8 \\ 3x = 16 \\ x = \frac{16}{3}$

$\frac{6x}{4} = 8 \\ 4 \times \frac{6x}{4} = 4 \times 8 \\ 6x = 32 \\ x = \frac{32}{6} \\ x = \frac{16}{3}$
