One question from this skill's own question bank, shown with its full working.
Solve x + 7 = 12.
Working: Subtract 7 from both sides: x = 12 − 7 = 5.
This usually appears in Junior High School algebra work, after learners have practised simplifying expressions and before more advanced equation topics. It supports the type of problem-solving often tested in the BECE.
