The value of y is 3.
What is equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).
Parts of an Equation
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.
Given:
(1/3)y2 + 12 = 5x
As,
x=3
(1/3)y^2+12=15
(1/3)y^2=15-12
(1/3)y^2=3
y^2=3*3
y^2=9
y=3
