Solve the Equation: Understanding -3 - X = 4

Question

Solve for X:

$-3-x=4$

00:05 Let's find the value of X.

00:08 Rearrange the equation so only X is on one side.

00:16 Now, let's group similar terms together.

00:24 Change negative numbers to positive if needed.

00:35 Remember, negative times negative gives a positive.

00:39 And positive times negative results in a negative.

00:43 Great job! That's how you solve this problem.

To solve the equation $-3 - x = 4$ , let's follow these steps:

Start by isolating $x$ . We will first eliminate the $-x$ term from the left side by adding $x$ to both sides of the equation. This gives us:

$-3 = 4 + x$

Now, subtract $4$ from both sides to solve for $x$ . This step ensures $x$ is isolated:

$-3 - 4 = x$

$-7 = x$

Hence, the solution to the given equation is $x = -7$ .

Reviewing the choices, the correct choice is , which is $-7$ .
