Question

the sum of three rational numbers - 2 upon 3, 3 upon 4, x is 1 upon 4. find the value of x​

Answer 1

Answer:

$x = \frac{11}{12}$

Step-by-step explanation:

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

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

$x = \frac{12 + 8 - 9}{12}$

$x = \frac{11}{12}$

Answer 2

$\frac{ - 2}{3} + \frac{3}{4} + x = \frac{1}{4} \\ \\ \implies \frac{ - 8 + 9}{12} + x = \frac{1}{4} \\ \\ \implies \: \frac{1}{12} + x = \frac{1}{4} \\ \\ \implies \: x = \frac{1}{4} - \frac{1}{12} \\ \\ \implies \: x = \frac{3 - 1}{12} \\ \\ \implies \: x = \frac{2}{12} \\ \\ \implies \: x = \frac{1}{6}$
