<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>

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,

Here, like terms are -3y and -5y
And 2x and -7x
Group the like terms

Combine the like terms

Thus the given expression is simplified
- 4(20+22)
- 4(40+2)
This expression are equivalent to 4(42)
