4= 1/3 (4x+9)

4 = \frac{1}{3} (4 x + 9)

x = \frac{3}{4}

Decimal Notation

x = 0.75

Solution steps

4 = \frac{1}{3} (4 x + 9)

Switch sides

\frac{1}{3} (4 x + 9) = 4

Multiply both sides by

3

4 x + 9 = 12

Move

9

to the right side

4 x = 3

Divide both sides by

4

x = \frac{3}{4}

\frac{x}{2} = 2 + \frac{x - 25}{5}

x^{2} + 4 x + 5 = - 6 x + 5

x \cdot 4190 = 360000

x^{2} - 32 = 0

128 x + 62 - 51 + 16 = 46 x - 20 + 15 - 9
