Question

3x + 8y =7
2x + 9y =1​

Answer 1

we can solve this by elimination method

let 3x+8y=7--–eq-1

and 2x+9y=1----eq-2

multiplying eq 1 and 2 by 2&3respectivly

6x+16y=14,--eq–3

6x+27y=3,--eq–4

subtracting both eq3 from eq4

0+11y=-11

y=-1

putting value of y in eq–2

2x+9×-1=1

2x-9=1

2x=10

x=10÷2

hence x=5,y=-1
