Step-by-step explanation:

first by elimination method

x-2y=-2

4x-3y=12

first we will multiply 4 by equation 1

4(x-2y=-2)

therefore 4x-8y=-8

now,

4x-8y=-8

+ 4x-3y=12

-. +. -

__________

-5y=-20

y=-20+5

y=-15 this is equation 3

now put equation 3 in equation 2

4x-3(-15)=12

4x +45=12

4x=12-45

4x=-33

X=-33/4

x=-8.2
