Jawab:
C. 70
Penjelasan dengan langkah-langkah:
[tex]\frac{5}{x} + \frac{2}{7} = \frac{5}{14} \\ \\\frac{5}{x} = \frac{5}{14} - \frac{2}{7}\\ \\\frac{5}{x} = \frac{5}{14} - \frac{4}{14}\\ \\\frac{5}{x} = \frac{1}{14}\\ \\x = 5 \times 14\\ \\x = 70[/tex]
Jawaban : C
[tex]\sf \frac{5}{x} +\frac{2}{7} =\frac{5}{14} \\\\\frac{5\cdot7}{7x} +\frac{2x}{7x} =\frac{5}{14}\\\\\frac{35}{7x} +\frac{2x}{7x} =\frac{5}{14}\\\\\frac{35+2x}{7x} =\frac{5}{14} \\\\\frac{35+2x}{x} =\frac{5}{2}\\\\5x=2(35+2x)\\\\5x=70+4x\\\\5x-4x=70\\\\x=70[/tex]
Maka nilai x adalah 70 [C.]
