35x+2=24−20x

Answer 1

For Question 7, we start with the equation:

\[ 2x + 12 - 3x = 27 \]

The first step in solving this equation is to combine like terms on the left side. This looks like:

\[ (2x - 3x) + 12 = 27 \]

This can be written as:

\[ -x + 12 = 27 \]

Now let's evaluate the provided options based on what has the same first step (combining like terms):

1. Option 1: \( 2x + 12 = -3x - 27 \) (not the same first step)
2. Option 2: \( 2(x - 5) + 2x = 10 \) (not the same first step, requires distribution)
3. Option 3: \( 2x + 12 = 27 \) (same first step; we can directly combine)
4. Option 4: \( 4x - 17 + 2x = 9 \) (not the same first step)

The correct answer for Question 7 is Option 3: \( 2x + 12 = 27 \).

---

For Question 8, we start with the equation:

\[ 7(5x + 2) = -4(6 - 5x) \]

Using the Distributive Property, we expand both sides:

Left side: \[ 7(5x + 2) = 35x + 14 \]

Right side: \[ -4(6 - 5x) = -24 + 20x \]

Thus, we can simplify the original equation to:

\[ 35x + 14 = -24 + 20x \]

Now let's evaluate the options provided:

1. Option 1: \( 35x + 14 = -24 + 20x \) (this is correct)
2. Option 2: \( 5x + 14 = 6 + 20x \) (not correct)
3. Option 3: \( 35x + 2 = -24 - 5x \) (not correct)
4. Option 4: \( 35x + 14 = -24 - 20x \) (not correct)
5. Option 5: \( 35x + 2 = 24 - 20x \) (not correct)

The correct answer for Question 8 is Option 1: \( 35x + 14 = -24 + 20x \).
