Q. Solve for x.Assume the equation has a solution for x.−px+r=−8x−2x=□
Identify System and Goal: Identify the given system of equations and the goal of solving for x.\begin{align*}\{-p\cdot x+r&=-8\cdot x-2\},\[1ex] \{x&=\square\}:\end{align*}We need to find the value of x that satisfies both equations.
Combine Like Terms: Combine like terms in the first equation to isolate x. −p⋅x+r=−8⋅x−2 Add p⋅x to both sides to get all x terms on one side. r=−8⋅x+p⋅x−2 r=x⋅(−8+p)−2
Isolate x in the Equation: Isolate x in the equation.r=x(−8+p)−2Add 2 to both sides.r+2=x(−8+p)Divide both sides by (−8+p) to solve for x.x=−8+pr+2
