Question

2 television and 4 DVDs cost $5480. 1 DVD player and 1 television cost $1970. How much does 1 television cost​

Answer 1

Answer:

The cost of one television is $1200.

We can use multiple equations to find the cost of one television.

Let's denote the cost of one television as T and the cost of one DVD as D.

We have two equations:

$2T+4D=5480\\T+D=1970$

We can use equation 2 to express D in terms of T:

$D=1970-T$

We can now substitute it back into the other expression;

$2t+4(1970-T)=5480$

$2T+7880-4T=5480\\-2T=-2400\\T=\dfrac{-2400}{-2} \\T= 1200$

So, the cost of one television is $1200.
