• Two algebraic expressions are linked using the equal to (=) symbol to form an algebraic equation. Because polynomials appear on both sides of the equal sign, an algebraic equation is sometimes called a polynomial equation. Variables, coefficients, constants, and algebraic operations like addition, subtraction, multiplication, division, and exponentiation are all part of an algebraic equation.

Given

Cost of 3 microwave oven and 2 LED TV , Cost of 2 microwave oven and 5 LED TV

Find

Cost of 1 microwave oven

Solution

Let microwave oven cost=x

Let LED TV cost               =y

Acc to question

3x+2y=60900...(1)

2x+5y=101,100...(2)

In eq-1 multiply by 5 and eq-2 multiply by 2

15x+10y=304500...(3)

4x+10y=202200....(4)

Substraction method

11x=102300

x=$\frac{102300}{11}$

x=9300
