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

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

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

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

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

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)

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)
