who can solve this system of equations algebraically? 10 pts!!!?

2x-5y=4

3x-4y=-1

------------

Simultaneous equations !

6x-15y=12

-6x+8y=2

------------ Adding!

-7y=14

y=-2

If y = -2 then taking

2x-5y=4. Substitute y= -2into this

2x-5(-2)=4

2x+10 =4

2x. =4-10

2x. =-6

x. = -3

Tiffany: you ought to pay extra interest on your math type. 5X-Y=-5; 25x-5y=-25 3x-5y=-3; 3x-5y=-3 We now replace each and all of the signs and indications on the backside and subtract it from the exceptional to get 22X=(-22); X=-a million. We sub.-a million for x in the two: 5(-a million) -y=-5; -5-Y=-5; Y=0; X=-a million. that may not the prevalent equation; even yet it is going to in uncomplicated terms paintings employing -a million and nil. 2. 3X-2y =-5 We multiply this with the help of a -2 to get -6x +4y=-10 6X-3y= 2 6x-3y= 2; Y=-8; 3x-2(-8)=5; 3X=5-sixteen; X=-11/3 answer is (-11/3,,-8)
