Question

12x-6=10x+15+3
Me ajudem rápido​

Answer 1

Explicação passo-a-passo:

a) 12x - 6 = 10x + 15 + 3

12x - 6 = 10x + 18

12x - 10x = 18 + 6

2x = 24

x = 24/2

x = 12

b) 4x + x /4 = 12

16x + x = 48

17x = 48

x = 48/17

c) 2x - 8 + 4 = 4x + 3

2x - 4 = 4x + 3

2x - 4x = 3 + 4

-2x = 7

x = -7/2

d) 10x + 3x - 3 + 5 = 2x - 15

13x + 2 = 2x - 15

13x - 2x = -15 - 2

11x = -17

x = -17/11

e) x - 18 + 2 = 5x + 4

x - 16 = 5x + 4

x - 5x = 4 + 16

-4x = 20

x = 20/-4

x = -5
