AYUDAAAAA PORFAAAA

Answer 1

Respuesta:

a)x = 2

b) x = 10

c) x = 6

Explicación paso a paso:

a.

5(x + 2) = 20

5x + 10 = 20

5x = 20-10

5x = 10

X = 10/5

X = 2

b)

9 + (x – 4) = 15

9 + x - 4 = 15

5+ x = 15

x = 15-5

x = 10

c.

5 – (x + 2) = –3

5 - x - 2 = - 3

3 - x = - 3

3 + 3 = x

6 = x
