2n + 8 - n = 20 Solve for n in the equation 2n + 8 - n = 20 Step 1: Group the n terms on the left hand side: (2 - 1)n = n Step 2: Form modified equation n + 8 = + 20 Step 3: Group constants: We need to group our constants 8 and 20. To do that, we subtract 8 from both sides n + 8 - 8 = 20 - 8 Step 4: Cancel 8 on the left side: n = 12
