Question

5x +3y= -11,2x +4y = -10​

Answer 1

Step-by-step explanation:

5x + 3y =-11 -------(1)

2x +4y = -10 ------(2)

equation (1) ×2. 10x+6y = -22

equation (2)×5. 10x+20y=-50

subtract them we get

6y-20y= -22+50

-14y = 28

y= -2

put y=-2 in equation (2)

2x+4(-2)= -10

2x-8= -10

2x = -10+8= -2

x=-1
