Question

1.5a + 6 = 9a + 12 please answer quick i hate math

Answer 1

Answer:

-0.8

Step-by-step explanation:

First move the variable terms to one side of the equal sign. I always move the smallest to the largest.

$1.5a + 6 = 9a + 12 \\ - 1.5a \: \: \: \: \: \: \: \: \ \: - 1.5a$

Solve and move the constants to opposite side. I'm going to subtract 12 from both sides.

$6 = 7.5a + 12 \\ - 12 \: \: - 12$

Now solve for a by dividing both sides by 7.5

$\frac{ - 6}{7.5} = \frac{7.5a}{7.5}$

$a = - 0.8$
