Pairs of Equations
- Linear equations that contain expressions on one side and numbers on the other can be solved by transposing terms from one side to the other or by performing same mathematical operations on both the sides.
Solve 2x – 7 = 3
2x – 7 = 3
Transposing –7 from LHS to RHS, we obtain
2x = 3 + 7 = 10
⇒ x = 5 …
