Question

how many solutions does 5(2x + 4)=5(2x - 3) have? none two

Explanation:

Step1: Expand both sides

Expand $5(2x + 4)$ to get $10x+20$, and expand $5(2x - 3)$ to get $10x-15$. So the equation becomes $10x + 20=10x-15$.

Step2: Subtract $10x$ from both sides

$(10x + 20)-10x=(10x-15)-10x$. This simplifies to $20=-15$, which is a false statement.

Answer:

None
