Answer:

y = -4

Explanation:

The initial expression is:

-13 = 4y + 3

So, we need to substract 3 from both sides of the equation:

-13 - 3 = 4y + 3 - 3

-16 = 4y

Then, dividing both sides by 4, we get:

-16/4 = 4y/4

-4 = y

Therefore, the solution of the system is y = - 4.

thus 4(a+4) = 6a

solve for "a"
