Question

3x – 2 = 4x + 9

5x -3 + x = 2x + 9

17x – 7x = x + 18

x + x – 4 = 17 – 2x + 1

x + 2x + 3 – 5x = 4x – 9

5x + 6x – 16 = 3x + 2x - 4

5x + 4 = 3x – 2x + 4



por favor me ajudem​

Answer 1

Explicação passo-a-passo:

A\

$3x - 2 = 4 - 9 \\ 3x = 4 - 9 + 2 \\ 3x = 4 + 2 - 9 \\ 3x = 3 \\ x = \frac{3}{3 } \\ x = 1$

Answer 2

a) 3x-2 = 4x+9

3x-4x= 9+2

-x = 11

b) 5x-3+x = 2x+9

5x+x-2x = 9-3

4x = 6

x = 6/4

c) 17x–7x = x+18

10x+x = 18+7

11x = 25

x = 25/11

d) x+x –4 = 17–2x+1

x+x+2x = 1+17+4

4x = 22

x = 22/4

e) x+2x+3–5x = 4x–9

x+2x-5x-4x = -9-3

-6x = -12

x = -12/6

x = 2

f) 5x+6x–16 = 3x+2x-4

5x+6x-3x-2x = -4+16

6x = 12

x = 12/6

x = 6

g) 5x+4 = 3x–2x+4

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

4x = 0
