Question

Solve by elimination method. 2x + 4y = - 10 and 5x + 3y = - 11​

Answer 1

Answer:

(a)

$= 2x + 4y = 6xy$

(b)

$5x + 3y = 8xy$

This is answer

Answer 2

Answer:

take 2x+4y=-10 as equation 1

5x+3y=-11 as equation 2

now multiply equation 1 with 5 and equation 2 with 2 and subtract the result

we will be getting the valu of y which is -2

substitute y=-2 in equation 1 or two u will get the x value which is -1

The Anser Is y= -2

x= -1
