Equations with linear expressions in one variable only are known as linear equations in one variable.

An algebraic equation is an equality involving variables. It has an equality sign(=). The expression on the left of the equality sign is the Left Hand Side (LHS). The expression on the right of the equality sign is the Right Hand Side (RHS).

==========================================================

Solution:

Let Hasan bought 2x m of trouser material and 3x m of the shirt material.

Per metre selling price(S.P) of the trouser material = ₹90+90×12/100

= 90 + 1.2× 9

= 90 + 10.8

=₹100.80

Per metre selling price(S.P) of trouser of shirt material

= ₹50+ 50× 10/100

= ₹ 50 + 5

=₹55

Given: total amount of sale= ₹ 36660

100.80 x (2x) + 55 x (3x) = ₹36660

201.60 x + 165x = 36660

366.60 x = 36660

X= 36660/366.60

x = 100

Trouser material = 2x m = (2×100)m = 200m.

Hasan bought 200 m of trouser material.

Answer 2

Step-by-step explanation:

Equations with linear expressions in one variable only are known as linear equations in one variable.

An algebraic equation is an equality involving variables. It has an equality sign(=). The expression on the left of the equality sign is the Left Hand Side (LHS). The expression on the right of the equality sign is the Right Hand Side (RHS).

==========================================================

Solution:

Let Hasan bought 2x m of trouser material and 3x m of the shirt material.

Per metre selling price(S.P) of the trouser material = ₹90+90×12/100

= 90 + 1.2× 9

= 90 + 10.8

=₹100.80

Per metre selling price(S.P) of trouser of shirt material

= ₹50+ 50× 10/100

= ₹ 50 + 5

=₹55

Given: total amount of sale= ₹ 36660

100.80 x (2x) + 55 x (3x) = ₹36660

201.60 x + 165x = 36660

366.60 x = 36660

X= 36660/366.60

x = 100

Trouser material = 2x m = (2×100)m = 200m.

Hasan bought 200 m of trouser material.
