    you have to solve system of 2 equations with 2 unknowns Multiply top equation by -2, then add the equation to eliminate variable A -2A -2B = -148 2A + 4B = 196 ----------------- 2B = 48 Solve this for B, then substitute back in to find A can you take it from here?

    B = 48/2 B = 24 A+B = 74 A+24 = 74 A = 74-24 = 50 There are 50 humans and 24 horses
