n - n = 10 - n Solve for n in the equation n - n = 10 - n Step 1: Group the n terms on the left hand side: (1 - 1)n = 0n = 0 Step 2: Form modified equation = - n + 10 Step 3: Group variables: We need to group our variables and -n. To do that, we add n to both sides + n = -n + 10 + n Step 4: Cancel -n on the right side: n = 10
