Clear Fraction by Multiplying: We have the equation (4r−6)/(r−7)=1/2. To solve for r, we need to clear the fraction by multiplying both sides of the equation by the denominator (r−7).Calculation: (4r−6)/(r−7)⋅(r−7)=1/2⋅(r−7)This simplifies to: 4r−6=(1/2)⋅(r−7)
Distribute 21 on Right Side: Distribute the 21 on the right side of the equation.Calculation: 4r−6=(21)×r−(21)×7This simplifies to: 4r−6=(21)×r−3.5
Move Terms to Isolate r: To isolate r, we need to get all the r terms on one side and the constants on the other. Let's move the (1/2)×r term to the left side by subtracting it from both sides.Calculation: 4r−(1/2)×r−6=−3.5This simplifies to: (8/2)×r−(1/2)×r−6=−3.5
Combine Like Terms: Combine like terms on the left side of the equation.Calculation: (28−21)⋅r−6=−3.5This simplifies to: (27)⋅r−6=−3.5
Add 6 to Both Sides: Add 6 to both sides to isolate the term with r.Calculation: (27)∗r−6+6=−3.5+6This simplifies to: (27)∗r=2.5
Multiply by Reciprocal: Multiply both sides by the reciprocal of (27) to solve for r.Calculation: r=2.5×(72)This simplifies to: r=75
