Question

Resuelve las ecuaciones de primer grado:
6 + 2 (3x – 4) = 7 (x – 1) + 4
x=?

5 – (3x + 2) = 2 (x + 1) – 9
x=?

Answer 1

6 + 6x - 8 = 7x - 7 + 4

-2 + 6x = 7x -7 + 4

-2 + 6x - 7x = -3

6x - 7x = -1

x = 1

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

3_3x = 2x + 2 - 9

3 - 3x - 2x = -7

-5x = -7 -3

-5x = -10

x=2
