Question

solve by cross multiplication 3x+4y=5,
6x-4y=-14​

Answer 1

Answer:

x=1

y=-2

Step-by-step explanation:

x. y. -1

3. 4. 5

6. -4. - 14

x/|-14*4-(-4)*5|=y/|-14*3-6*5=-1/|-4*3-6*4|

x/-56+20 = y/-42-30 = -1/-12-24

x/-36= -1/-36

36x=-36

x= -1

similarly

y/-72= -1/-36

36y=-72

y= -72/-36= 2
