Question

a) (15a +9)= 3
b) (6x - 10) = ( -30)​

Answer 1

Respuesta:

a = - 2 / 5

x = - 10 / 3

Explicación paso a paso:

a ) .

( 15 a + 9 ) = 3

15 a + 9 = 3

15 a = 3 - 9

15 a = - 6

a = - 6 / 15

a = - 2 / 5

b ) .

( 6 x - 10 ) = ( - 30 )

6 x - 10 = - 30

6 x = - 30 + 10

6 x = - 20

x = - 20 / 6

x = - 10 / 3
