this might help you

Answer 2

Algebraic representation of a pair of linear equations:

The representation of word problems in the form of linear equations is called an algebra representation.

For this we use the following steps:

Step 1.
Identify the variable quantities in the given statement and let these be X and Y.

Step 2.
Use the Conditions given in the problem to frame equations in the unknowns X and Y.

SOLUTION:

Let the cost of 1 kg apple be x and cost of 1 kg grapes be y.

Condition 1:

2x+y = 160........(1)

Condition 2:
4x+9y = 300.....(2)

Equation 1 & 2 represent this situation algebraically.
