Question

I need the step by step on how to solve
x-y=10
X+2y=4

Answer 1

Your answer:

x - y = 10 ----(i)

x + 2y = 4 -----(ii)

By using elimination method, we get,

x - y = 10

- x + 2y = 4

y = 6 -----(iii)

Adding equation (i) and (iii), we get

x - 6 = 10

x = 10 + 6

∴ x = 16

Hence, x = 16 and y = 6.

Answer 2

Answer:

(x,y)=(44/3,14/3).

Step-by-step explanation:

Given equations are: x-y=10 ------------(1)

                                   x+2y=4  ----------(2)

(1) => x=y+10   ---------------(3)

(2) => x+2y=4

    => (y+10)+2y=4      [From (3)]

    => 3y=14

    => y=14/3.

Now put y=14/3 in (3):

=> x=(14/3)+10

=> x=44/3

∴(x,y)=(44/3,14/3).
