Question

Son ecuaciones linealesss necesito ayudaaa

Answer 1

Explicación paso a paso:

b.

- x - 9 = 2*x + 15

- 9 - 15 = 2*x + x

- 24 = 3*x

- 24/3 = x

- 8 = x

c.

4*(x - 2) = 2*(x + 9)

4*x - 8 = 2*x + 18

4*x - 2*x = 18 + 8

2*x = 26

x = 26/2

x = 13

d.

5 - 3*x = - 2*x + 1

5 - 1 = - 2*x + 3*x

4 = x

e.

2 + 3*(x + 1) = - 10

2 + 3*x + 3 = - 10

3*x + 5 = - 10

3*x = - 10 - 5

3*x = - 15

x = -15/3

x = -5
