Let's go through the steps again to ensure clarity and correctness.<br /><br />Given the equations:<br />\[ 2y + 4.4x = -5 \]<br />\[ y = -2.2x + 4.5 \]<br /><br />First, substitute \( y = -2.2x + 4.5 \) into the first equation:<br />\[ 2(-2.2x + 4.5) + 4.4x = -5 \]<br /><br />Now, distribute the 2:<br />\[ 2 \cdot (-2.2x) + 2 \cdot 4.5 + 4.4x = -5 \]<br />\[ -4.4x + 9 + 4.4x = -5 \]<br /><br />Combine like terms:<br />\[ -4.4x + 4.4x + 9 = -5 \]<br />\[ 0 + 9 = -5 \]<br />\[ 9 = -5 \]<br /><br />This is a contradiction, which means there is no solution to the system of equations. Therefore, the statement is not true, and there is no solution.<br /><br />So, the final answer is:<br />\[ \text{The statement is not true. There is no solution.} \]
