Solve 12/5 + 12/25 * r = 3 + 1/10 * r

Evaluate

\frac{12}{5} + \frac{12}{25} r = 3 + \frac{1}{10} r

Multiply both sides of the equation by LCM

(\frac{12}{5} + \frac{12}{25} r) \times 50 = (3 + \frac{1}{10} r) \times 50

Calculate

More Steps

120 + 24 r = (3 + \frac{1}{10} r) \times 50

Calculate

More Steps

120 + 24 r = 150 + 5 r

Move the expression to the left side

120 + 24 r - 5 r = 150

Move the expression to the right side

24 r - 5 r = 150 - 120

Add and subtract

More Steps

19 r = 150 - 120

Add and subtract

19 r = 30

Divide both sides

\frac{19 r}{19} = \frac{30}{19}

Solution

r = \frac{30}{19}

Alternative Form

r \approx 1.578947
