Question

Resuelve las siguientes preguntas con procedimiento

a.- x-5(2x-3)=(x-1)+4

b.- 2(x-5) / 3 +4=5x-2

c.- 3(x-4)+10=13-x

Answer 1

1)

X - 5(2x - 3) = (x-1) + 4

X - 10x + 15 = x + 3

- 9x + 15 = x + 3

15 - 3 = x + 9x

12 = 10x

6/5 = x

2)

2(x - 5) /3 +4 = 5x + 2

2x - 10 / 3 + 4 = 5x + 2

2x - 10 +12 = 15 x + 6

2x + 2 = 15x + 6

- 4 = 13 x

- 4/13 = x

3)

3(x - 4) + 10 = 13 - x

3x - 12 +10 = 13 - x

3x - 2 = 13 - x

4x = 15

X = 15/4
