Question

x-3y=0 and x-y=1 solve by elimination

Answer 1

Answer:

x= 3/2 , y= 1/2

Step-by-step explanation:

x - 3y = 0 ......1

x - y = 1 ......2 (-) - + - (subtract ....2 from .....1 )

----------------------

0 -2y = -1

y= 1/2

put y= 1/2 in statement ......1

x - 3(1/2) = 0

x - 3/2 = 0

x = 3/2

Answer 2

Answer:

x = 1  1/2,  y = 1/2

Step-by-step explanation:

 x - 3y = 0(equation 1)

 x -   y  = 1(equation 2)

to eliminate x, we subtract equation 1 from equation 2

x  -   y = 1

- x  - 3y = 0

x - x = 0

(-y) - (-3y) = -y + 3y = 2y

2y  = 1

y = 1/2

so now we know y

x - y = 1

x - 1/2 = 1

x = 1 + 1/2

x = 1  1/2

∴x = 1  1/2,  y = 1/2
