Answer:

a = 1

Step-by-step explanation:

Given

15a - 2 = 3a + 10 ( subtract 3a from both sides )

12a - 2 = 10 ( add 2 to both sides )

12a = 12 ( divide both sides by 12 )

a = 1

Answer:

[tex]a = 1[/tex]

Step-by-step explanation:

15a - 2 = 3a + 10

Take out 3a from both sides:

15a - 3a         3a - 3a

12a                    0

12a - 2 = 10

Add 2 to both sides:

-2 + 2                    10 + 2

0                                  12

12a = 12

Divide 12 by both sides:

[tex]\frac{12a}{12}   =   \frac{12}{12}[/tex]

a  =  1
