Class 10 Pair of Linear Equations Quiz

Solve the following pair of linear equations using substitution method: 3x + 4y = 10, 2x - y = 5

• x = 4, y = 1

• x = 2, y = 3

• x = 3, y = 1

• x = 5, y = 2

Find the solution to the pair of linear equations using substitution: 5x - 2y = 8, 3x + 2y = 10

• x = 4, y = 3

• x = 1, y = 2

• x = 2, y = 4

• x = 3, y = 5

Use the elimination method to solve the pair of linear equations: 2x + 3y = 11, 4x - 2y = 10

• x = 5, y = 2

• x = 3, y = 4

• x = 1, y = 5

• x = 2, y = 3

Solve the following system of linear equations using elimination: 3x - 2y = 7, 2x + 5y = 11

• x = 5, y = 2

• x = 2, y = 4

• x = 3, y = 1

• x = 1, y = 3

Determine whether the system of equations is consistent or inconsistent: 4x + 3y = 10, 8x + 6y = 20

• The system of equations is inconsistent.

• The system of equations is dependent.

• The system of equations has no solution.

• The system of equations is consistent.
