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
