Question

36). Which is the standard form of linear equations x = -5? * O X + 5 = 0 O 1.x - 5 = 0 O 1.x + 0.y + 5 = 0 O 1.x + 0.y = 5​

Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

Which is the standard form of linear equations in two variables: y – x = 5

(i) 1.y – 1.x – 5 = 0

(ii) 1.x – 1.y + 5 = 0

(iii) 1.x + 0.y + 5 = 0

(iv) 1.x – 1.y – 5 = 0

CONCEPT TO BE IMPLEMENTED

The standard form of linear equations in two variables is

EVALUATION

Here the given equation of the linear equation is

y – x = 5

Which can be rewritten as

Which is of the standard form

FINAL ANSWER

Hence the correct option is

(ii) 1.x – 1.y + 5 = 0

Answer 2

Answer:

The standard form of linear equation in 1 variable is ax + b = 0

The standard form of linear equation in 2 variables is ax + by + c = 0
