Question

solve using method of elimination 2 X + 3 Y is equals to 23 5x -20 =8y​

Answer 1

Answer:

Step-by-step explanation:

2x+3y=23 .....1

5x-20=8y......2

so bring y to rhs

5x-8y=20

now multiply eqn 1 with 5 and eqn 2 with 2

so we get

10x+15y=115

10x-16y=40

so

eliminating 10x and 10x in both eqn

-y=75

y=-75

apply y in eqn 2

5x=8*-75+20=-580
