The equation would be: (50+x)/4 = 11+ x, where x equals the number of added photos The equation is saying that you currently have 50 pieces of art. When you add x photos, one-fourth of the new total number of pieces of art ( (50+x)/4 ) is equal to the 11 original photos plus the x that you add ( The new total number of photos is represented as 11+x). Cross multiply and solve to get x = 2. Therefore, 2 photos must be added, and the total number of pieces of art is 50 + 2 = 52 pieces of art.
