Transcribed Image Text:3x + 4y = -23 2y – x = - 19 2.) What is the solution (x, y) to the system of equations above? A) (-5, -2) B) (3,-8) C) (4, -6) D) (9,-6)
Expert Solution
Step 1

Ans.1 We have given equations

x+y=-9  ......(i)

x+2y=-25 ........(ii)

Subtracting equation (i) from (ii)

2y-y=-25--9

y=-25+9

y=-16

Put value of y in equation (i) 

x-16=-9

x=16-9

x=7

So, we get 

x=7
