Take the second equation already set to y and substitute it into the first equation for y...

3x + (6 - 4x) = 1  ... now we simplify
3x + 6 - 4x = 1  .....now combine like terms
-x + 6 = 1    .....

Y=6-4x
sub 6-4x for y

3x+y=1
3x+(6-4x)=1
3x+6-4x=1
3x-4x+6=1
-x+6=1

3rd option

5.65 times 3.4 estimate
lidiya [134]
We can round 5.65 up to 6 and 3.4 down to 3.
3 * 6 = 18
now let's see how close our estimate is to the real answer
5.65 * 3.4 = 19.21
Our answer was pretty close to the real answer!

Hope I helped!

Answer:

Ani age is 21

Biju age is 18

Step-by-step explanation:

let Ani age be X

let Biju age be Y

the difference of their age is 3

i.e X - Y = 3......,....(equ. 1)

let Dharam age be A

let Cathy age be B

i.e A = 2x

B = y/2

the difference of their age is 30

Y/2 - 2x = 30..... (equ. 2)

from equ.1 X = ( 3+y).........( equ.3)

y/2 - 2(3+y) = 30

y/2 - 6 + 2y = 30

multiply both side by 2

y - 6 + 2y = 60

y + 2y = 60 - 6

3y = 54

Y = 18

from equ.3

X = 3+Y where y is 18

X = 3+18 = 21
