Recall

Expressions, substitution and like terms — objective 1

Maths4U Original · Short practice

Consider \(E=5 x + 4 y + 52\).

Find the coefficient of x after collecting like terms.

Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.
