Question

.. Is 5y x 2y=40 a linear equation in one variable ?​

Answer 1

Step-by-step explanation:

no it is not

Answer 2

Given :-

• 5y × 2y = 40

Aim :-

• To find y and to check if the given equation is a linear equation in 1 variable.

We know that, a variable is the unknown value in the equation and can take up any value accordingly, to satisfy the equation.

Here, the equation is

5y × 2y = 40

Multiplying,

5 × y × 2 × y = 40

10y² = 40

Transposing 10 to the other side

y² = 40 ÷ 10

y² = 4

Transposing the power,

y = √4

y = 2

5y × 2y = 40 is a Linear equation as there is only involvement of 1 variable (y).

Hope it helps!

Have a great day!
