Answer 2

Let's solve each of these equations step by step:

1. 34 + 2x = 76

To isolate x, we'll subtract 34 from both sides: 34 + 2x - 34 = 76 - 34 2x = 42

Now, divide both sides by 2: 2x/2 = 42/2 x = 21

So the solution to the equation is x = 21.

2. 324 / (17p + p) = 3

Simplifying the denominator: 324 / (18p) = 3

Now, we'll cross-multiply: 3 * 18p = 324

Multiply: 54p = 324

Divide both sides by 54: 54p / 54 = 324 / 54 p = 6

The solution to the equation is p = 6.

3. 132 - z = 84

To solve for z, we'll subtract 132 from both sides: 132 - z - 132 = 84 - 132 -z = -48

Multiplying both sides by -1 to isolate z: (-1)(-z) = (-1)(-48) z = 48

The solution to the equation is z = 48.

4. 6 * 15y = 450

Divide both sides by 6 to isolate y: (6 * 15y) / 6 = 450 / 6 15y = 75

Divide both sides by 15: (15y) / 15 = 75 / 15 y = 5

The solution to the equation is y = 5.

5. 12 / 4 - 12 = 0

Performing the division first: 3 - 12 = 0

Subtract: -9 = 0

This equation is not true. There is no solution that satisfies this equation.

To summarize:

1. x = 21
2. p = 6
3. z = 48
4. y = 5
5. No solution exists.
