Answer 2

Alright, let's tackle these one by one.

1. $0.5 + 3 = 0.2x$

First, add 0.5 and 3 to get 3.5. Then, divide both sides by 0.2 to solve for $x$.

2. $-0.4x - 14 = 0.3x$

First, add 14 to both sides, and then combine like terms. Afterward, isolate $x$ by dividing by the coefficient of $x$.

3. $6.9 - 9x = 5x - 33.1$

Combine like terms by adding $9x$ to both sides. Then, subtract 6.9 from both sides to isolate $x$.

4. $4.7 - 8x = 4.9 - 10x$

Combine like terms by adding $10x$ to both sides and subtracting 4.7 from both sides. Then, isolate $x$ by dividing by the coefficient of $x$.

Remember, in each step, perform the same operation on both sides of the equation to keep it balanced. Let me know if you need help with the calculations!
