alleryWhich of the following is a linear equation in one variable?
Ax² + 1 = 0
B2x + y = 5
C5x − 3 = 7
Dxy = 10
Answer & Solution
Correct answer: C. 5x − 3 = 7
A linear equation in one variable has exactly one variable and the highest power of that variable is 1. Only 5x − 3 = 7 satisfies both conditions.
