Question

1) 3 x + 5 = 2 (x - 2) + 12
2) 2 x + 4 = 3 (x + 5) + x - 2
3) 5x – 2 (x - 3) = 17 - 10
4) 4x-7 + 5 x + 24 = x + 7

Answer 1

Respuesta:

1) 3x + 5= 2(x-2) +12

3x+5 = 2x - 4 + 12

3x + 5 = 2x + 8

x = 3

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

2x +4 = 3x +15 +x -2

2x + 4 = 4x +13

-9 = 2x

-9/2 = x

3) 5x -2 (x-3) =17 - 10

5x -2x +6 = 17 -10

3x +6 = 7

3x = 1

x= 1/3

4) 4x -7 +5x +24 = x + 7

9x +17 = x + 7

8x = -10

x = -10/8

Answer 2

Respuesta:

30x+20x+15x+12x/60 = x-17

77x/60 = x - 17

77x = 60X - 1020

17X = -1020

X= -1020/17

X = - 60
