r = 4.44444 \dots

Solution steps

2 \frac{1}{4} r = 10

Convert mixed numbers to improper fractions:

2 \frac{1}{4} = \frac{9}{4}

\frac{9}{4} r = 10

Multiply both sides by

9 r = 40

Divide both sides by

r = \frac{40}{9}

Convert improper fractions to mixed numbers:

\frac{40}{9} = 4 \frac{4}{9}

r = 4 \frac{4}{9}

\frac{2 x}{3} + \frac{3}{4} - \frac{x}{4} = \frac{x}{2} - \frac{1}{4}

2 + y = 4

25 - 5 (4 + 3 x) = 15

x, 2 x + 2 y - 8 = 0

x - 1 = - 4
