Answer:

x = 27

Step-by-step explanation:

3x - 4y = 65

3x = 65 + 4y

3x = 65 + 4 (4)

3x = 65 + 16

3x = 81

x = 27 $[ \ x = \frac{81}{3}\ ]$

Simplify -3y+2x-5y-7x

Sphinxa [80]

<h3><em><u>Simplify -3y+2x-5y-7x is:</u></em></h3><h3>-8y - 5x</h3>

<em><u>Solution:</u></em>

<em><u>Given that, we have to simplify</u></em>

$-3y + 2x-5y-7x$

We can simplify the above expression by combining the like terms

Like terms are terms that has same variable ( with same exponent) with same or different coefficient

From given,

$-3y + 2x-5y-7x$

Here, like terms are -3y and -5y

And 2x and -7x

Group the like terms

$-3y-5y+2x-7x$

Combine the like terms

$-8y -5x$

Thus the given expression is simplified
