Question

determina el valor de x ​

Answer 1

Respuesta:

Explicación paso a paso:

4x - 15 + 6x + 25 = 180

4x + 6x - 15 + 25 = 180

10x + 10 = 180

10x = 180 - 10

10x = 170

x = 170/10

x = 17

3x + 45 + 4x + 35 = 360

3x + 4x + 45 + 35 = 360

7x + 80 = 360

7x = 360 - 80

7x = 280

x = 280/7

x = 40
