Given equation: Start with the given equation.2d+4=10+5dWe need to isolate the variable d on one side of the equation.
Isolate variable : Subtract from both sides to move all d terms to one side.\newline222d + 444 - 555d = 101010 + 555d - 555d\newlineThis simplifies to:\newline−3-3−3d + 444 = 101010
Move ddd terms to one side: Subtract 444 from both sides to isolate the term with ddd.\newline−3d+4−4=10−4-3d + 4 - 4 = 10 - 4−3d+4−4=10−4\newlineThis simplifies to:\newline−3d=6-3d = 6−3d=6
Simplify equation: Divide both sides by −3-3−3 to solve for ddd.−3d−3=6−3\frac{-3d}{-3} = \frac{6}{-3}−3−3d=−36This simplifies to:d=−2d = -2d=−2
