Answer 1

Respuesta:

1)

$y = \frac{5x}{4} \\ 0 = \frac{5x}{4} \\ \frac{5x}{4} = 0 \\ 5x = 0 \\ 5x + \div 5 = 0 \div 5 \\ x = 0$

2)

$y = 3x + 3 \\ 0 = 3x + 3 \\ - 3x = 3 \\ x = - 1$

3)

$y = 2x + 4 \\ 0 = 2x + 4 \\ - 2x = 4 \\ x = - 2$

4)

$y = \frac{x}{2} + 4 \\ 0 = \frac{x}{2} + 4 \\ 0 = x + 8 \\ - x = 8 \\ x = - 8$

5)

$4x + y = 8 \\ 4x + y - 8 = 8 - 8 \\ 4x + y - 8 = 0$

Espero haberte ayudado!
