10n - 9n + 8n - 7n + 6n = 10 - 9 + 8 - 7 + 6

10n - 9n + 8n - 7n + 6n = 10 - 9 + 8 - 7 + 6

Solve for n in the equation 10n - 9n + 8n - 7n + 6n = 10 - 9 + 8 - 7 + 6

Step 1: Group the n terms on the left hand side:
(10 - 9 + 8 - 7 + 6)n = 8n

Step 2: Group the constant terms on the right hand side:
10 - 9 + 8 - 7 + 6 = 8

Step 3: Form modified equation
8n = + 8

Step 4: Divide each side of the equation by 8
8n/8 = 8/8

n = 1
