(2x2 + 5x + 3) + (8x3 + 6x + 5) = 8x3 + 2x2 + 11x+ 8

(5x2 + 3x + 2) + (2x2 + 4x + 5) = 10x4 + 7x2 + 7

(2x3 + 3x2 + 2x + 9) + (5x3 + 7x + 1) = 7x3 + 3x2+ 9x + 10

(6x3 + 9x2 + x + 10) + (4x2 + 10x + 3) = 6x3 + 13x2 + 11x + 13

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
