Question

solve each equation. 9) a + 5 = -4 what is the value of a? a = -9 a = -1 a = 9 a = 1

Explanation:

Step1: Isolate the variable a

Subtract 5 from both sides of the equation $a + 5=-4$. So we get $a+5 - 5=-4 - 5$.

Step2: Simplify the equation

On the left - hand side, $a+(5 - 5)=a$, and on the right - hand side, $-4-5=-9$. So $a=-9$.

Answer:

$a = - 9$
