Answer:
R = 13/3
Explanation:
Based on the given conditions, formulate: 2 x r - 10 = -1 1/3
Apply Multiplicative Distribution Law: 2r - 10 = -1 - 1/3
Multiply both sides of the equation by the common denominator: 2r x 3 -10 x 3 = -3 - 3/3
Reduce the fractions: 2r x 3 - 10 x 3 = -3 - 1
Multiply the monomials: 6r - 10 x 3 = -3 - 1
Calculate the product or quotient: 6r - 10 x 3 = -3 - 1
Rearrange unknown terms to the left side of the equation: 6r = -3 - 1 + 30
Calculate the sum or difference: 6r = 26
Divide both sides of the equation by the coefficient of variable: r = 26/6
Cross out the common factor: r = 13/3
Answer: r = 13/3
