Question

quien resuelve los siguientes ejercicios
1.- 2+5(x-13)=x-3
2. 75-5x=3x+3
3. 2x-1=3(2x-15)

Answer 1

2 + 5 (x - 13) = x - 3

2 + 5x - 65 = x - 3

5x - x = - 3 + 65 - 2

4x = 60

x = 60/4

x = 15
------------------------------

75 - 5x = 3x + 3

- 5x - 3x = 3 - 75

- 8x = - 72

x = -72/-8

x = 9
---------------------------------------
2x - 1 = 3 (2x - 15)

2x - 1 = 6x - 45

2x - 6x = - 45 + 1

- 4x = - 44

x = -44/-4

x = 11
