• 4X + 3 = 21 – 2X
• 9X – 4= 2X
• X + 5 X = - 10 + 3
• 4X – 9X + 2 = 7X – 5X – 9
• 3X – 8X + 9X = 12 – 7X

e) x=12/11

Answer 2

Respuesta:

4x+3 = 21–2x

4x+2x = 21-3

6x = 18

x = 18/6

x =  3

9x–4 = 2x

9x-2x = 4

7x = 4

x = 4/7

x+5x = -10+3

x+5x = -10+3

6x = -7

x = -7/6

4x–9x+2 = 7x–5x–9

4x-9x-7x+5x = -9-2

-7x = -11

x = -11/-7

x = 11/7

3x–8x+9x = 12–7x

3x-8x+9x+7x = 12

11x = 12

x = 12/11
