The Deep Dive
To tackle the system of equations \(y - 3x = 2\) and \(2y - 5x - 10 = 0\), you can substitute the first equation into the second. From the first equation, express \(y\) as \(y = 3x + 2\), then substitute this into the second equation to solve for \(x\). After finding \(x\), substitute back to find \(y\). You'll discover that \(x = 4\) and, substituting back, \(y = 14\). Now, let's address the inequality \(0 < 3x - 6 \leq 12\). Break it down: First, \(3x - 6 > 0\) leads to \(x > 2\). Then, \(3x - 6 \leq 12\) simplifies to \(x \leq 6\). Thus, the solution is combined as \(2 < x \leq 6\), meaning \(x\) can be any number greater than 2 and up to 6! Happy solving!
