-1/2(2n+4) + 6 = -9 + 4(2n+1) First thing you must do is distribute to the parentheses. (-1/2*2n) + (-1/2*4) + 6 = -9 + (4*2n) + (4*1) -1n - 2 + 6 = -9 + 8n + 4 Now combine like terms. -n + 4 = 8n - 5 Subtract 4 from both sides. -n = 8n - 9 Subtract 8n from both sides. -9n = -9 Divide both sides by -9. n = 1 The value of n is 1.
