Question

PLEASE HELP

Answer 1

Hey there! I'm happy to help!

We want to get the a all by itself. For me, I always like to have the variable on the left side, so first, let's just flip this around.

$\frac{a-13}{-6} =1$

What we want to do is get all of the constants (numbers without variables) on the right side. This will leave a all on its own.

We see that the quantity a-13 is being divided by -6. To undo this, we will just multiply both sides by -6. This will cancel out that -6 and get us closer to having the a isolated.

$\frac{a-13}{-6} *-6=1*-6\\\frac{a-13}{1}=-6\\a-13=-6$

Now we add 13 to both sides to undo the -13 on the left side.

$a-13+13=-6+13$

$a+0=7\\a=7$

Have a wonderful day and keep on learning! :D

Answer 2

Answer: 7

Step-by-step explanation:

1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6:  1= a-13/-6 ==> -6=a-13

2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13

3. you know -6+13 equals 7 right? so the answer is a=7
