To solve, rearrange the first equation: y=112x then substitute y into the second equation. 3x + 4(112x) = 24 3x+448x = 24 5x = 20 x = 4 So Bob is age 4. sub in known value into either equation. 2(4)+y=11 8+y=11 y=3 So Alice is age 3. Then check: 2(4)+(3) is equal to 11 3(4)+4(3) is equal to 24. So there is the solution
