besarnya nilai x pada persamaan [tex] \frac{4}{5} + \frac{2}{x } = 2[/tex] adalah

[tex] \frac{4}{5} + \frac{2}{x} = 2 \\ \frac{4x + 10}{5x} = 2 \\ 4x + 10 = 2 \times 5x \\ 4x + 10 = 10x \\ 10 = 10x - 4x \\ 10 = 6x[/tex]
x = 10/6
x = 1 4/6
x = 1 2/3
semoga membantu

Bab Persamaan Linear

4/5 + 2/x = 2
2/x = 10/5 - 4/5
2/x = 6/5
x = 5 . 2/6
x = 5/3
x = 1 2/3
