Question

a) y + 2 = 11

b) 2x + 7 = 5

c) x2 − 4x + 4 = 0

d) −y + 2 = 11 e) x + 3 = 5

f) x2 − 25 = 0

Answer 1

¡Hola!

resolvemos:

a) y + 2 = 11

$y = 11 - 2$

$y = 9$

b) 2x + 7 = 5

$2x = 7 - 5$

$2x = 2$

$x = 1$

c) x2 − 4x + 4 = 0

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

$2x - 4x + 4 = 0$

$- 2x + 4 = 0$

$- 2x = - 4$

d) −y + 2 = 11

$- y = 11 - 2$

$- y = 9$

e) x + 3 = 5

$x = 3 - 5$

$x = 2$

f) x2 − 25 = 0

$x \times 2 - 25 = 0$

$2x - 25 = 0$

$2x = 25$

Espero ayudarte＼(^-^ )
