Beyond the Answer
To find an expression equivalent to \( 10k + 17 - 7j = 10 - 11k \), we'll rearrange the equation. First, we can move all terms involving \( k \) to one side and everything else to the other side. Rearranging gives us \( 10k + 11k = 10 - 17 + 7j \), simplifying to \( 21k = -7 + 7j \). Dividing everything by 7 gives us \( 3k = j - 1 \). From this, we can derive that \( 0 - 7j + k + 1 = 0 \), which correlates to the expression \( 0-7 j+k+1 \). So the correct answer is \( 0 - 7 j + k + 1 \). Now, let's dive into some relevant insights: Did you know that equations like this one can represent lines in a graph? The variables \( k \) and \( j \) can be thought of as coordinates in a 2D plane! Solving the equation helps you visualize relationships between these variables—it's like drawing a treasure map where each point gives you clues to find arcs of relationships! When manipulating equations like this, a common mistake is forgetting to correctly distribute or combine like terms. Always double-check your algebra! A misstep while simplifying can lead to answers that seem right but ultimately lead you down the wrong path. Keep your work organized, and it becomes much easier to catch those pesky errors!
