7n + 4 + n - 5 = 63
Solve for n in the equation 7n + 4 + n - 5 = 63
Step 1: Group the n terms on the left hand side:
(7 + 1)n = 8n
Step 2: Group the constant terms on the left hand side:
4 - 5 = -1
Step 3: Form modified equation
8n - 1 = + 63
Step 4: Group constants:
We need to group our constants -1 and 63. To do that, we add 1 to both sides
8n - 1 + 1 = 63 + 1
Step 5: Cancel 1 on the left side:
8n = 64
Step 6: Divide each side of the equation by 8
8n/8 = 64/8
n = 8
