Solve 5r-1= 7r 11

Evaluate

5 r - 1 = 7 r \times 11

Multiply the terms

5 r - 1 = 77 r

Move the variable to the left side

5 r - 1 - 77 r = 0

Subtract the terms

More Steps

- 72 r - 1 = 0

Move the constant to the right side

- 72 r = 0 + 1

Removing 0 doesn't change the value,so remove it from the expression

- 72 r = 1

Change the signs on both sides of the equation

72 r = - 1

Divide both sides

\frac{72 r}{72} = \frac{- 1}{72}

Divide the numbers

r = \frac{- 1}{72}

Solution

r = - \frac{1}{72}

Alternative Form

r = - 0.013 \dot{8}
