Question

1) Resolver las siguientes ecuaciones.
a) 2×+5= 19
b) 3×-4= 20
c) 5×-3= 3×+7
d) 4×+9+×= 24​

Answer 1

Respuesta:

Explicación paso a paso:

2x + 5 = 19

2x = 19 - 5

2x = 14

x = 14/2

x = 7

3x - 4 = 20

3x = 20 + 4

3x = 24

x = 24/3

x = 8

5x - 3 = 3x + 7

5x - 3x = 7 + 3

2x = 10

x = 10/2

x = 5

4x + 9 + x = 24

5x + 9 = 24

5x = 24 - 9

5x = 15

x = 15/5

x = 3
