Answer 3

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

1. 3x + 7 = x

First, we want to isolate x on one side of the equation. To do that, we need to get all the x terms on one side and the constant terms on the other side.

Subtract x from both sides: 3x - x + 7 = x - x

This simplifies to: 2x + 7 = 0

Now, subtract 7 from both sides to isolate 2x: 2x + 7 - 7 = 0 - 7

This simplifies to: 2x = -7

Finally, divide both sides by 2 to solve for x: 2x/2 = -7/2

x = -7/2

So, the solution to the first equation is: x = -7/2

2. -5m + 24 = m

Similar to the first equation, we want to isolate m on one side of the equation:

Add 5m to both sides: -5m + 5m + 24 = m + 5m

This simplifies to: 24 = 6m

Now, divide both sides by 6 to solve for m: 24/6 = 6m/6

4 = m

So, the solution to the second equation is: m = 4

3. -16 - m = -2m

Again, we want to isolate m on one side:

Add m to both sides: -16 - m + m = -2m + m

This simplifies to: -16 = -m

Now, multiply both sides by -1 to solve for m (to make m positive): -1*(-16) = -m*(-1)

This simplifies to: 16 = m

So, the solution to the third equation is: m = 16

To summarize:

1. x = -7/2
2. m = 4
3. m = 16
