Simultaneous Equations

Math ⇒ Algebra

Simultaneous Equations starts at 8 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Simultaneous Equations. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A number is 4 more than another number. Their sum is 16. What are the numbers?

A shop sells pencils and pens. 2 pencils and 3 pens cost $12. 1 pencil and 2 pens cost $7. How much does one pen cost?

A system of equations has exactly one solution. What does this mean about the lines represented by the equations?

A system of equations has no solution. What does this mean about the lines represented by the equations?

If 2x + 3y = 12 and x - y = 1, what is the value of x?

If 3x + 2y = 12 and 2x - y = 1, what is the value of y?

If x + y = 8 and x - y = 4, what is the value of x?

If x + y = 9 and x - y = 1, what is the value of y?

Solve for x and y: 4x - y = 9, 2x + y = 7.

Solve for x: 2x + 3y = 13, x - y = 1.

Solve for y: 2x + y = 9, x - y = 1.

Solve for y: 3x + 2y = 12, x - y = 1.

Solve the following system of equations: x + y = 10, x - y = 2.

Solve the system: x + y = 7, x - y = 1.

Solve: 2x + 3y = 13, 4x - y = 9.

Solve: 5x + 2y = 20, 3x - 2y = 4.

Solve: x + 2y = 11, 3x - y = 4.
