Write equation: Write down the equation.6d−(211)=2d−(213)We need to solve for d by isolating it on one side of the equation.
Subtract variable terms: Subtract 2d from both sides to move the variable terms to one side.6d−2d−(211)=2d−2d−(213)Simplify the equation by combining like terms.4d−(211)=−(213)
Combine like terms: Add (211) to both sides to isolate the variable term.4d−(211)+(211)=−(213)+(211)Simplify the equation by combining like terms.4d=−(213)+(211)
Add to isolate variable term: Calculate the right side of the equation.4d=−(213)+(211)4d=−(22)4d=−1
Calculate right side: Divide both sides by 4 to solve for d.44d=4−1d=4−1
