Question

which of the following is simple equation
a. 7x+4=11 b. x-y=11 c.a+b+c=0 d. x²+1=0​

Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

Which of the following is simple equation

a. 7x+4 = 11

b. x - y = 11

c. a + b + c = 0

d. x² + 1 = 0

CONCEPT TO BE IMPLEMENTED

Simple Equation : In study of mathematics a simple equation is an equation containing one unknown quantity, and that quantity only in the first degree

EVALUATION

First equation is 7x + 4 = 0

So in this equation there is one variable and of first degree

So the equation is simple equation

Second equation is x - y = 11

So in this equation there are two variables

So the equation is not simple equation

Third equation is a + b + c = 0

So in this equation there are three variables

So the equation is not simple equation

Fourth equation is x² + 1 = 0

So in this equation there is one variable but of degree degree

So the equation is not simple equation

FINAL ANSWER

Hence the correct option is d. x² + 1 = 0
