Question

find y if 5y+1/2=3/4 ​

Answer 1

Answer:

y=5/4

Step-by-step explanation:

5y=3-2/4

5y=1/4

y=5/4

Answer 2

Answer:

1/20

Step-by-step explanation:

let's start by subtracting 1/2 from both sides.

$\implies \sf \: 5y + \dfrac{1}{2} - \dfrac{1}{2} = \dfrac{3}{4} - \dfrac{1}{2}$

$\implies \sf \: 5y + 0 = \dfrac{3 - 2}{4}$

$\implies \sf 5y = \dfrac{1}{4}$

Divide both sides by 5.

$\implies \sf \dfrac{5y}{5} = \dfrac{1}{4} \times \dfrac{1}{5}$

$\implies \sf y = \dfrac{1}{20}$

Important Points:-

• polynomials : Polynomial are variable based dialect in the language of maths.

• In a common language , polynomials are defined as a string of variables and numbers put together.

• Highest power of a polynomial is called degree of polynomial.

• A constant polynomial is nothing but a monomial with degree zero.

• Equation: A condition or a constraint placed on x and y coordinates.

• Curve: A union of points that satisfy a particular condition.

• Remainder theorem: When p(x) is divided by (x - a) then the remainder is given by p(a).
