Answer 2

It seems like you've provided a list of equations. Let's solve each one step by step:

1. $5x = 10$ Divide both sides by 5: $x = 2$

2. $-\frac{3}{4}y = 6$ Multiply both sides by $-\frac{4}{3}$: $y = -8$

3. $-4x = 1.2$ Divide both sides by $-4$: $x = -0.3$

4. $x + 6 = 10$ Subtract 6 from both sides: $x = 4$

5. $x + 4 = 3x$ Subtract $x$ from both sides: $4 = 2x$ Divide by 2: $x = 2$

6. $-0.2x + 7 = -1.6x$ Add $0.2x$ to both sides: $7 = -1.4x$ Divide by $-1.4$: $x = -5$

7. $2x + 8 = 6x - 2$ Subtract $2x$ from both sides: $8 = 4x - 2$ Add 2 to both sides: $10 = 4x$ Divide by 4: $x = 2.5$

8. $6 - 2c = 3c - 10$ Add $2c$ to both sides: $6 = 5c - 10$ Add 10 to both sides: $16 = 5c$ Divide by 5: $c = 3.2$

9. $-4 + 3k = 8k + 5$ Subtract $3k$ from both sides: $-4 = 5k + 5$ Subtract 5 from both sides: $-9 = 5k$ Divide by 5: $k = -1.8$

10. $-10x + 3 = -1 - 8x$ Add $8x$ to both sides: $8x - 10x + 3 = -1$ Simplify: $-2x + 3 = -1$ Subtract 3 from both sides: $-2x = -4$ Divide by $-2$: $x = 2$

Please double-check these solutions as there might be a possibility of errors in the equations provided.
