What is negative 3 minus x equals negative 10

Answer: x = 7

Step-by-step explanation:

-3-x=-10

Add 3 to both sides

-x=-7

Divide each side by - 1

X = 7

In order to solve this equation, let's write it out in number form:

-3 - x = - 10

In order to isolate 'x' we need to ensure that there is only 'x' on one side. We can get rid of the - 3 by adding 3 to both sides:

-3 + 3 - x = - 10 + 3

-x = - 7

Because there are negatives on both sides, you can simply cancel them out:

x = 7
