Question

ECUACIONES:
3x+1 /3=2
2x+2=1x+10
9x+11=2(+3x+17.5)

Answer 1

Respuesta:

$3x + \frac{1}{3} = 2 \\ 3x = 2 - \frac{1}{3} \\ 3x = \frac{6 - 1}{3} \\ 3x = \frac{5}{3}$

$x = \frac{5}{3} \times \frac{1}{3} \\ x = \frac{5}{9}$

Explicación paso a paso:

$2x - x = 10 - 2 \\ x = 8$

9x + 11 = 2(3x + 17.5)

9x + 11 = 6x + 35

9x - 6x = 35 - 11

3x = 24

x = 24/3

x = 8
