Question

2(х+7)+4х9(3-у)+1511(х+6)+3415(у+9)-7у18(5+х)+12х22(у+4)-19у

Answer 1

1) 6х+14
2)27-9у+15=-9у+42
3)11х+100
4)8у+135
5)30х+90
6)3у+88

Answer 2

To simplify the given expression, let's break it down step by step:

2(x + 7) = 2x + 14

4x9(3 - у) = 36x - 36у

1511(x + 6) = 1511x + 9066

3415(у + 9) = 3415у + 30735

-7у18(5 + х) = -126у - 126х

12х22(у + 4) = 264х + 88у

-19у

Now, let's combine all the simplified terms:

2x + 14 + 36x - 36у + 1511x + 9066 + 3415у + 30735 - 126у - 126х + 264х + 88у - 19у

Combining like terms:

(2x + 36x + 1511x - 126х - 126х + 264х) + (14 - 36у + 9066 + 30735) + (-36у + 3415у + 88у - 19у)

= 1699x - 46х + 379у + 50

So, the simplified expression is 1699x - 46х + 379у + 50.
