5x + 8y = –29 (equation 1)
7x – 2y = –67 multiple 4 on both sides the result is:
28x - 8y = -268 (equation 2)
adding up equation 1 and 2 the result is:
33x = -297
x = -297/33 = -9
5(-9) + 8y = -29
8y = -29 + 45 = 16
y = 2
The solution for the system 5x + 8y = –29 7x – 2y = –67 is (-9, 2)

4x^6(7x^5 + 4y^2)

= (4x^6)(7x^5) + (4x^6)(4y^2)

= 28x^11 + 16x^6y^2
