Question

by using elimination method
iv. 5x-y=13
3x+2y=13

Answer 1

Answer:

X= 3. Y=2

Step-by-step explanation:

i. multiply 2 in the first step

we get: 10x-2y=26

ii. add both the equations

we get: 13x=39

x=39/13

x=3

iii. substitute x=3 in eqn 2

3(3)+2y=13

9+2y=13

2y=13-9

2y=4

y=4/2

y=2

hence the required soln is (x,y)= (3,2)

Answer 2

Answer:

y ki value h 3 or x ki value h 16/5
