Question

Solve simultaneous equations-2x + y =4 3x-2y=13

Answer 1

Answer:

-2x+y = 4

3x-2y =13

let us add to equations

-2x+y+3x-2y=4+13

x-y=17

Add -2x+y=4 and x-y=17

-2x+y+x-y=4+17

-x = 21

therefore, x= -21

substitute the value of x in either of the equations to get the value of y

Considering x-y=17

-21-y=17

or, -y=17+21

therefore, y= -38
