enter answer
question 12
solve and check the equation.
5x - 5 = 20
enter answer

Explanation:

Question 11

Step1: Isolate the variable a

Divide both sides of the equation $5a=-10$ by 5. So, $a = \frac{-10}{5}$.

Step1: Add 5 to both sides

To isolate the term with x, add 5 to both sides of the equation $5x - 5=20$. We get $5x-5 + 5=20 + 5$, which simplifies to $5x=25$.

Step2: Solve for x

Divide both sides of the equation $5x = 25$ by 5. So, $x=\frac{25}{5}$.

Answer:

$a=-2$
