Question

Equation x - 5 = 10

What operation is currently in the equation :subtract 5:

What's the inverse operation :add 5:

Use the the inverse operation to isolate the variable x
:x - 5 = 10:

:x - 5 + 5 = 10 + 5:

Simplify both sides of the equation to find the solution
X = *blank 1*

Options for blank 1

A 0
B 10
C 15
D -10

Check your solution *blank 2* -5 = 10

Options for blank 2

A 10
B 0
C -10
D 15

Answer 1

Let's solve the equation step by step.

1. The equation you have is \( x - 5 = 10 \).
2. The operation currently in the equation is subtracting 5.
3. The inverse operation is adding 5.
4. To isolate the variable \( x \), you can use the inverse operation:

\[
x - 5 + 5 = 10 + 5
\]

5. Simplifying both sides gives:

\[
x = 15
\]

So, the answer for blank 1 is **C 15**.

Now let's check the solution:

Substitute \( x = 15 \) back into the original equation:

\[
15 - 5 = 10
\]

This simplifies to \( 10 = 10 \), which is true.

Since the left side equals the right side, the solution is confirmed.

For blank 2, we can see that \( 10 \) is the correct value when checking. Therefore, the answer for blank 2 is **A 10**.
