Question

3 X + 2 Y is equal to 48 x + 5 Y is equal to 9 cross multiplication method​

Answer 1

Answer:

x=123/15; y=-39/5

Step-by-step explanation:

3x +2y = 48+5y=9

so,at first,

48+5y= 9

5y= 9-48=-39

y = -39/5

then, 3x+2y=9

or, 3x+ 2(-39/5)= 9

or, 3x -78/5=9

or, 3x= 9+(78/5) = (45+78)/5= 123/5

or, x = 123/15
