help me pls
21x-2y=15.....(1) 13x-y=10(1)

Answer 1

Answer:

X=1 Y=3

Step-by-step explanation:

21x-2y=15 i

13x-y=10 ii

by multiplying equation ii by 2

we get 26x -2y=20 iii

now by subtracting equation iii and i we get

5x=5

x=1

substituting the value of x in equation ii

we get 13-y=10

-y=-3

y=3
