Question

0.24x−0.74=−1.1
0.24x=
Add 0.74 to both sides.
x=
Divide both sides by 0.24.

Answer 1

−3x−9=−21
−3x=
Add 9 to both sides.
x=
Divide both sides by −3.

Answer 2

Let's solve the equation step by step.

Starting with the equation:

\[
0.24x - 0.74 = -1.1
\]

1. **Add 0.74 to both sides:**

\[
0.24x - 0.74 + 0.74 = -1.1 + 0.74
\]

This simplifies to:

\[
0.24x = -0.36
\]

2. **Divide both sides by 0.24:**

\[
x = \frac{-0.36}{0.24}
\]

Now calculate that division:

\[
x = -1.5
\]

So the final solution is:

\[
x = -1.5
\]

Answer 3

Let's solve the equation step by step.

Starting with the equation:

\[
-3x - 9 = -21
\]

1. **Add 9 to both sides:**

\[
-3x - 9 + 9 = -21 + 9
\]

This simplifies to:

\[
-3x = -12
\]

2. **Divide both sides by -3:**

\[
x = \frac{-12}{-3}
\]

This simplifies to:

\[
x = 4
\]

So the final solution is:

\[
x = 4
\]
