Question

Resuelve las ecuaciones:
2×=×+15
3×+3=2×+3
5×=60
4×+2=40
3×-5=×+7

Answer 1

Respuesta:

x = 15

x = 0

x = 12

x = 9,5

x = 6

Explicación paso a paso:

2x = x + 15

2x - x = 15

x = 15

3x + 3 = 2x + 3

3x - 2x = 3 - 3

x = 0

5x = 60

x = 60/5

x = 12

4x + 2 = 40

4x = 40 - 2

4x = 38

x = 38/4

x = 19/2

x = 9,5

3x - 5 = x + 7

3x - x = 7 + 5

2x = 12

x = 12/2

x = 6
