Question

solve the system of equation 2x-3y=13 7x‐2y=20​

Answer 1

Answer

2x−3y=13...(1)

7x−2y=20....(2)

Let us use the elimination method to the given system of equations.

Multiply (1) by 2 and (2) by 3. And subtract both the equations.

−17x=−34

4x−6y=2621x−6y=60−+−

x=

−14

−34

=+2

Substitute the value of x in equation (1), we have

y=−3

Hence x=2 and y=−3
