2. C
Step-by-step explanation:
Haudicjduyshsvdbcbis 2cn and yes it is
Step-by-step explanation:
If (5) = 3
Then (10) = 6
Because 5 x 2 = 10 so 3 x 2 = 6
Answer:
ans: x= 11/4 and y= 11/8
Step-by-step explanation:
4x=6y=6 mean
4x= 6 and 6y= 6 so, 6-6=0 i.e
4x - 6y = 0 say equation ....1
and given
2x + 5y = 11 say equation ....2
to solve by eliminating methods,
multiply equation....2 by 2 and subtract from ....1
i.e
4x - 6y =0
4x + 10y= 22

0+ (-)16y = - 22
y = -22/-16
y = 11/ 8
to get , x put y in either equation 1 or 2
I.e x= 11/4
this value of x and y satisfy both equations
