Question

A system of equations is shown in the box. What are the values of x and y that will make the system true?

Answer 1

Explanation:

Ans:x=2 and y=5

this is called the elimination method in linear graphs and simultaneous linear equations.

1. multiply each equation by suitable number so that they have the same coefficient but in this case, the coefficient is the same

2. subtract/add from the equations

3.solve the new equation

4.substitute the value of x/y into any equation above and solve it
