Scenario: Players enter a mystical realm where numbers and equations are scattered throughout. They must navigate through an enchanted forest, solving absolute value equations to progress. The forest is filled with floating equations, each presenting a unique challenge. Players must simplify the equations, isolate the absolute value expressions, and find both positive and negative solutions. Along the way, they battle mathematical creatures and interact with wise mathematicians who provide guidance and additional equations. Rewards and clues help players advance. The ultimate goal is to reach the Tree of Equations, restore its power, and break the curse that has plagued the realm. Through Equation Enigma, players practice solving absolute value equations while developing critical thinking and problem-solving skills. Task: Solve the equation. |2x+5|−5=5

The following initial value problem of a first order linear system $x' = 3x - 2y$ $x(0) = 1$, $y' = 3x + 4y$, $y(0) = -2$ can be converted into an initial value problem of a 2nd order differential equation for $x(t)$. It is: a) $x'' - 7x' + 6x = 0$, $x(0) = 1$, $x'(0) = -2$ b) $x'' - x' + 6x = 0$, $x(0) = 1$, $x'(0) = 1$ c) $x'' - x' + 6x = 0$, $x(0) = 1$, $x'(0) = 2$ d) $x'' - 7x' + 6x = 0$, $x(0) = 1$, $x'(0) = 7$ e) $x'' + 7x' + 6x = 0$, $x(0) = 1$, $x'(0) = 0$

A simple model of these oscillations has been proposed by Sel'kov (1968). In dimensionless form, the equations are $\dot{x} = -x + ay + x^2y$ $\dot{y} = b - ay - x^2y$ 7.3 POINCARÉ-BENDIXSON THEOREM 207 where x and y are the concentrations of ADP (adenosine diphosphate) and F6P (fructose-6-phosphate), and a,b > 0 are kinetic parameters. Construct a trapping region for this system. Solution: First we find the nullclines. The first equation shows that $\dot{x} = 0$ on the curve $y = x/(a + x^2)$ and the second equation shows that $\dot{y} = 0$ on the curve $y = b/(a + x^2)$. These nullclines are sketched in Figure 7.3.4, along with some representative vectors. y y=b/(a+x²)
