1) -4+x=2-5x-4+3

2) 8+2x-5=4x+1

3) 3.(2-x)+4=5-3x+10-x

4) -2.(3x+4)+4.(3x-4)= -(-5x+4)-3x

Answer 1

Respuesta:

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

$8 + 2x - 5 = 4x + 1 \\ 2x - 4x = 1 - 8 + 5 \\ - 2x = - 2 \\ x = \frac{ - 2}{ - 2} \\ x = 1$

$3(2 - x) + 4 = 5 - 3x + 10 - x \\ 6 - 3x + 4 = - 3x + 10 - x \\ - 3x + 3x + x = 10 - 6 - 4 \\ x = 0$
