6-108.

Solving the equation ultimately involves isolating *x* to determine its value.

If both strategies are working towards isolating *x* through different methods, will both strategies work?

Does one strategy require less work to isolate *x*?

Is the strategy of adding 5 to both sides rather than subtracting 7 a more efficient and direct method?

7 = 3*x* − 5

+5 +5

*x* = 4
