Question

x/4-10+x+x/6+3=180° find the answer fastly​

Answer 1

Answer:

$\frac{x}{4} - 10 + x + \frac{x}{6} + 3 = 180. \\ \frac{x}{4} + \frac{x}{6} - 10 + 3 = 180. \\ \frac{x \times 3}{4 \times 3} + \frac{x \times 2}{6 \times 2} - 10 + 3 = 180. \\ \frac{3x}{12} + \frac{2x}{12} - 10 + 3 = 180. \\ \frac{5x}{12} - 10 + 3 = 180. \\ \frac{6x}{12} - 7 = 180. \\ 6x - 7 = 180 - 6x. \\ 180 = 180.(6x \: eliminated \: from \\ both \: the \: sides). \\ hence \: proved.$
