Question

solve the following system of equations by eliminating 3x-5y=1,5x+2y=15​

Answer 1

Step-by-step explanation:

3x-5y=1....×(5)

5x+2y=15×(3)

equation (1)-(2)

15x-25y=5

15x+6y=45

-. -. -

0. -31y=-40

y=40/31

put the value of y in equation (1)

3x-5×40/31=1

3x-200/31=1

(93x-200)/31=1

93x-200=31

93x=31×200

93x=6200

therefore x=6200/93.
