Question

Solve for m: -8 = m/-10 - 16

Answer 1

We have this equation:

-8 = m/-10 -1

We can add 8 at both sides:

-8 + 8 = m/-10 -16 + 8

0 = m/-10 -8

Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:

0 = m/-10 - 8*(-10)/-10

0 = m/-10 +80/-10

Now, we can delete all denominators

0 = m + 80

And we can say m = -80

Now, we can replace it to see if it's true:

-80/-10 - 16 = -8, so we know that's true

-80/-10 -16 = 8 - 16 = -8 ..

Answer 2

m = -80

Explanation:

Step 1: Define

-8 = m/-10 - 16

Step 2: Solve for m

1. Add 16 to both sides: 8 = m/-10
2. Multiply -10 on both sides: -80 = m
3. Rewrite: m = -80
