Question

Ayudaa son ecuaciones lineales

8(3x+2)-5(2x-1)=8-(9-3x)

7(x+3)-3(x-2)=16(2x-3)+19

8(1-x)-2(x+1)=3(2-2x)​

Answer 1

Explicación:

1.- 24x + 16 - 10x + 5 = 8 - 9 + 3x

14x + 21 = -1 + 3x

14x - 3x = - 1 - 21

11x = - 22

x = -2

2.- 7x + 21 - 3x + 6 = 32x - 64 + 19

4x + 27 = 32x - 45

27 + 45 = 32x - 4x

72 = 28x

0.3 = x

3.- 1 - x - 2x - 2 = 6 - 6x

- 3x - 3 = 6 - 6x

- 3x + 6x = 6 + 3

3x = 9

x = 3
