Explanation:

Step1: Combine like terms

$10x + 7x - 3 + 11 = 17x + 8$

Step2: Combine like terms

$4x - x + 4 + 9 - 1 = 3x + 12$

Step3: Combine like terms

$10x - 9x + 6 + 4 = x + 10$

Step4: Combine like terms

$3x + 15$ (already simplified)

Step5: Combine like terms

$12x - 9x + 2 + 10 - 5 = 3x + 7$

Step6: Combine like terms

$x + x + 2 + 3 = 2x + 5$

Step7: Combine like terms

$5x - 3x - x + 6 + 2 = x + 8$

Step8: Combine like terms

$x + 7$ (already simplified)

Step9: Combine like terms

$15x + 10$ (already simplified)

Step10: Combine like terms

$6x - 2x - 3x + 3 + 4 = x + 7$

Step11: Simplify and combine terms

$8x - 5x + 14 + 1 = 3x + 15$

Step12: Simplify and combine terms

$6x + 9x + 6 + 4 = 15x + 10$
