The value of x = ±1.
Step-by-step explanation:
Algebraic equation:
Algebraic expression:
- A polynomial which contains variables, coefficients and constants joined together using mathematical operations such as addition, subtraction, multiplication and division is called as algebraic expression.
Algebraic equation:
- An algebraic equation is a mathematical statement that contains two equated algebraic expression.
- The general form of algebraic equation is P=0 or P=Q where P and Q are polynomials.
Given expression is
27x = 81/3x
we need to find the value of x.
now rearrange the above equation
(27x)(3x) = 81
27(3x²) = 81
27(3x²)-81 = 0
81x²-81 = 0
81(x²-1) = 0
x²-1 = 0/81
x²-1 = 0
x² = 1
x = √1
x = ±1
Hence, the value of x = ±1.

Answer:
x=4/3
