The Deep Dive
To solve for \( y \), we first equate the corresponding components of the matrices: 1. From the first component, we have: \[ 4x = 15 + x \] Rearranging gives: \[ 4x - x = 15 \] \[ 3x = 15 \] \[ x = 5 \] 2. Now substituting \( x = 5 \) into the second component: \[ 5 = 2y \] Solving for \( y \) gives: \[ y = \frac{5}{2} = 2.5 \] Thus, the value of \( y \) is \( 2.5 \).
