Question 2 - Page 184 Using this formula can you solve this equation 2x + 3 = 4x + 5?Given equation 2x + 3 = 4x + 5 Comparing equation with Ax + B = Cx + D Thus, A = 2 B = 3 C = 4 D = 5 And, our solution is x = (๐ท โˆ’ ๐ต)/(๐ด โˆ’ ๐ถ) x = (๐Ÿ“ โˆ’ ๐Ÿ‘)/(๐Ÿ โˆ’ ๐Ÿ’) x = 2/(โˆ’4 + 2) x = 2/(โˆ’(4โˆ’2)) x = ๐Ÿ/(โˆ’๐Ÿ) x = (โˆ’2)/2 x = โ€“1 Thus, value of x is โ€“1
