Answer 2

It looks like you've provided a list of equations. It seems like you want to solve for the value of the variable "x" in each equation. Let's go through each equation one by one:

1. $4x = 24 + x$: To solve for x, you can subtract x from both sides: $4x - x = 24$ $3x = 24$ Now, divide both sides by 3 to isolate x: $x = 8$

2. $8x - 8 = 20 - 6x$: First, add 6x to both sides and add 8 to both sides: $8x + 6x = 20 + 8$ $14x = 28$ Now, divide both sides by 14 to solve for x: $x = 2$

3. $9 - 4x = 3x - 40$: Add 4x to both sides and add 40 to both sides: $9 + 40 = 3x + 4x$ $49 = 7x$ Divide both sides by 7 to find x: $x = 7$

4. $0.6x - 5.4 = -0.8x + 5.8$: Add 0.8x to both sides and add 5.4 to both sides: $0.6x + 0.8x = 5.8 + 5.4$ $1.4x = 11.2$ Divide both sides by 1.4 to solve for x: $x = 8$

5. $4.7 - 1.1x = 0.5x - 3.3$: Add 1.1x to both sides and add 3.3 to both sides: $4.7 + 3.3 = 0.5x + 1.1x$ $8 = 1.6x$ Divide both sides by 1.6 to find x: $x ≈ 5$

So, the solutions for the variables x in each equation are:

1. $x = 8$
2. $x = 2$
3. $x = 7$
4. $x = 8$
5. $x ≈ 5$
