variables to represent this statement.​

Answer 1

Answer:

$8x + 7y = 100$

this is the required expression

Answer 2

$\large{\boxed{\boxed{\sf{Solution}}}}$

★ $\sf{8x + 7y = 100 \ or \ 8x + 7y - 100 = 0}$

$\begin{gathered}\bf{\underline{\underline{Given :-}}}\\\end{gathered}$

8 apples and 7 oranges together cost Rs 100.

$\begin{gathered}\bf{\underline{\underline{To\:find}}}\\\end{gathered}$

linear equation in two variables to represent this statement.

$\large{\boxed{\boxed{\sf{Let's \: understand \: the \: concept \: 1st}}}}$

Here , 8 apples can be denoted with variable x in the linear equation as 8x.

7 oranges can be denoted with variable y in the linear equation as 7y.

And they together cost 100rs.

★$\tt\red{Together \ this \ can \ be \ written \ as :-}$

↬ 8x + 7y = 100
