Question

Resuelva cada ecuación lineal.
1) 2(x + 2) − 5(2x − 3) = 3






2) 10x − 4(x +1) = 13 + 3x






3) 5(2 − 3x) = 3(2 − 3x)

Answer 1

1)
2(x + 2) − 5(2x − 3) = 3

2x + 4 - 10x - 15 = 3

-8x = 18

x = -18/8

Simplificando...

x = -9/4


2)
10x − 4(x +1) = 13 + 3x

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

6x - 4 = 13 + 3x

3x = 17

x = 17/3

3)
5(2 − 3x) = 3(2 − 3x)

10 - 15x = 6 - 9x

4 = 6x

4/6 = x

Simplificando...

2/3 = x
