Opposite operation of multiplication = division.

Simply divide 65 by 5.45
Answer:

Step-by-step explanation:
So we have the system of equations:

And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.
We can see that the coefficient of x in the second equation is 15.
So, to match 15, we must multiply the first equation by 3. So:

Multiply:

And we're done!
Beths weekly income is 600$ per week.
600 / 0.4 = 240
T=cost of one television
D= cost of one DVD player
2t+3d= 1421
D=t(1/2)
Replace d by t(1/2)
2t+3(t1/2)= 1421
3.5 t = 1421
T= 691.7 $
