Using polynomials times monomials how do i set up the steps in this problem 4(2n + 3) - 3(n - 1) = 0 Get rid of the parentheses using the distributive property: Multiply the 4 times the 2n which gives 8n Multiply the 4 times the +3 which gives +12 Multiply the -3 times the n which gives -3n Multiply the -3 times the -1 which gives +3 So the equation is now free of parentheses: 8n + 12 - 3n + 3 = 0 Combine the 8n and the -3n to get 5n Combine the +12 and the +3 to get +15 5n + 15 = 0 Add -15 to both sides 5n + 15 = 0 -15 -15 ------------- 5n = -15 Divide both sides by coefficient 5 5n -15 -- = ----- 5 5 Cancel the 5's on the left, getting n, and divide -15 by 5 on the right, getting -3 n = -3 Edwin
