Answer:

2/3

Step-by-step explanation:

We know the value of y, so substitute y into the equation:

3x + (-4 + 11) = 9 --> remove parentheses

3x - 4 + 11 = 9

3x + 7 = 9 --> subtract 7 from 9

3x = 2 --> divide

x = 2/3

What is 2/4 + 4/5 - 7/10 ? Please help

Radda [10]

Make sure they have all common denominators
$\frac{2}{4} + \frac{4}{5} - \frac{7}{10}$

$\frac{2}{4} * \frac{5}{5} = \frac{10}{20}$

$\frac{4}{5} * \frac{4}{4} = \frac{16}{20}$

$\frac{7}{10} * \frac{2}{2} = \frac{14}{20}$

$\frac{10}{20} + \frac{16}{20} - \frac{14}{20}$

Add $\frac{10}{20} + \frac{16}{20} = \frac{26}{20}$
$\frac{26}{20} - \frac{14}{20} = \frac{12}{20}$

To simplify, you must find the largest common factor which 4
In $\frac{12}{20}$
12÷4=3 and 20÷4=5

The answer is $\frac{3}{5}$
