Resolver las ecuaciones
A 4x +6=7x-15
b x-3+2=8x-23
C -6x+10=x-8+x+2
D 8x+3= -4+7x-2

Answer 1

Resolvemos.

Ejercicio 1

4x + 6 = 7x - 15

15 + 6 = 7x - 4x

21 = 3x

7 = x

Ejercicio 2

x - 3 + 2 = 8x - 23

x - 1 = 8x - 23

23 - 1 = 8x - x

22 = 7x

22/7 = x

Ejercicio 3

-6x + 10 = x - 8 + x + 2

-6x + 10 = 2x - 6

10 + 6 = 2x + 6x

16 = 8x

2 = x

Ejercicio 4

8x + 3 = -4 + 7x - 2

8x + 3 = 7x - 6

8x - 7x = -6 - 3

x = -9
