Answer:

1. (4x+3y)

4x =  - 3y \\ x =  \frac{ - 3y}{4}

2.

 {(7xy - 9y)}^{2}  \\ (49xy - 81y) \\  y(49x - 81) = 0 \\ 49x - 81 = 0 \\ 49x =  81 \\ x =  \frac{81}{49}

3.

(8x + 9)(8x - 11) \\ either.8x =  - 9 \\  \:  \:  \:  \:  \: x =  \frac{ - 9}{8}  \\  \: or.8x - 11 = 0 \\ 8x = 11 \\ x =  \frac{11}{8}

4.

 {67}^{2}  = 4489

5. 78×86=6708

6.

 {74}^{2}  -  {66}^{2}  \\  = 6076 - 4356 = 1720

I hope it's help you
