The solution (B) x=79.
Rewriting the equation to find the solution -
(x+2)³/₄=27
Raising both sides of the equation with exponent ⁴/₃
((x+2)³/₄)⁴/₃ = 27⁴/₃
Cancelling the exponents on Left Hand Side of the equation. Writing the value on Right Hand Side of the equation in exponent form
x + 2 = (3³)⁴/₃
Cancelling 3 on Right Hand Side of the equation
x + 2 = 3⁴
Solving Right Hand Side of the equation
x + 2 = 81
Shifting 2 to Right Hand Side of the equation
x = 81 - 2
Performing subtraction on Right Hand Side of the equation
x = 79
Hence, the solution is (B) x=79.

Answer:
20/4
Step-by-step explanation:
10/2 = 20/4
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Given the equations:
x = 4y
x - 4y = 0 (1)
Also:
x - y + 3z = 3 (2)
And:
2x - 3y - z = -7 (3)
The solution to the equation is:
x = -4, y = -1 and z = 2
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
