2(2x - 3) + 2 + [?] = 7x - 4. What term makes this equation true for all values of x? 2(2x - 3) + 2 + [?] = 7x - 4
4x - 6 + 2 + ? = 7x - 4 {distributive property} 4x - 4 + ? = 7x - 4 {combined like terms} looks like ? = 3x, that will make both sides equal 4x - 4 + 3x = 7x - 4 {put 3x in for ?} 7x - 4 = 7x - 4 {combined like terms} - Algebra House
