The correct Answer is:
To solve the given problem step by step, we will start with the first equation and manipulate it to find the value of \(10y + 4x\). ### Step 1: Start with the given equation The first equation we have is: \[ 0.2x = 10 - 0.5y \] ### Step 2: Rearrange the equation We can rearrange this equation to bring all terms to one side: \[ 0.2x + 0.5y = 10 \] ### Step 3: Eliminate decimals To eliminate the decimals, we can multiply the entire equation by 20: \[ 20(0.2x) + 20(0.5y) = 20(10) \] This simplifies to: \[ 4x + 10y = 200 \] ### Step 4: Rearranging to find \(10y + 4x\) We can rearrange the equation to express it in the form \(10y + 4x\): \[ 10y + 4x = 200 \] ### Conclusion Thus, the value of \(10y + 4x\) is: \[ \boxed{200} \]
