Given: \(\frac{17+m}{43+m}=\frac{2}{3}\)
Cross multiply to get: \((3)(17+m)=(2)(43+m)\)
Expand to get: \(51+3m=86+2m\)
Subtract 51 from both quantities to get: \(3m=35+2m\)
Subtract 2m from both quantities to get: \(m=35\)
Answer: 35

Cross multiply and we get
51 + 3m = 86 + 2m
Taking all variables and all constants on one side, we get
3m - 2m = 86 - 51
m = 35
