Question

The difference of an integer x and (-9) is 6 find the value of x

Answer 1

x- (-9) = 6

or, x+9 = 6

or, x = 6 - 9

or, x = -3

Hence, the value of x is -3

Answer 2

$\mathfrak{\large{\underline{Answer :}}}$

$\boxed{x = - 3}$

$\mathfrak{\large{\underline{Explanation :}}}$

Given : Difference of x and - 9 is 6

To find : Value of x

$\textbf{\underline{According\:to\:the\:problem}}$

x - ( - 9) = 6

x + 9 = 6

x = 6 - 9

$\boxed{x = - 3}$

1)Equation : An open sentence which contains who is equal to (=) sign is called an equation.

e.g.x + 9 = 5

x + y + z = 16

2) Open sentence : A sentence for which we cannot decide whether it is true or false is called an open sentence .

3) Linear equation : an equation in which the exponent of the variable is 1 is called linear equation .

e.g 2x - 6 = 3x - 5

x + 9 = 6

4) Simple equation : Linear equation in one variable are called simple equations.

e.g 5x - 2 = 10

2y - 8 = 14
