Question

Por favor, me ajudem nesses cálculos:

a) -4x+ 3x+ 2x = 27- 3x

b) 10-3+2x = 15-3+4x

Answer 1

a) - 4x + 3x + 2x = 27 - 3x

- 4x + 3x + 2x + 3x = 27

- 4x + 8x = 27

4x = 27

x = 27/4

b) 10 - 3 + 2x = 15 - 3 + 4x

2x - 4x = 15 - 3 - 10 + 3

- 2x = 18 - 13

- 2x = 5 * (-1)

2x =  - 5

x = - 5/2

Answer 2

A) -4x+3x+2x = 27-3x

-4x+3x+2x+3x= 27

8x-4x = 27

4x = 27

X= 27/4

B) 10-3+2x = 15-3 +4x

-4x+2x = 15-3 -10+3

-2x = 12 -7 *(-1)

2x = -12 + 7

X = -5/2
