Question

Selve each system of equations using elimination method.
2x-9y=1
x-4y=1
​

Answer 1

Answer:

(x,y) = (5,1)

Step-by-step explanation:

2x-9y=1. --- (1)

x-4y=1. ---(2)

multiply eq.(2) ×2

2x-8y=2. ---(3)

eq.(1) - eq.(3)

= -y= -1

= y=1

put y=1 in eq.(2)

x-4y=1

x-4×1=1

x-4=1

x=1+4

x=5

(x,y) = (5,1)
