Question

5x + 3y =9 and 2x -3y = 12 find the value of x = ?​

Answer 1

$\huge\red{Solution}$

Given :-

Equation of line , 2x - 3ky = 6

point(3,-2) lies on the given line

Find :-

Value of k

Explanation

Let,

Point (3,-2) lies to line on the A point.

Its means that, this point satisfied of the given equation of line.

So, keep , x = 3 & y = -2 in given equation

2 × 3 - 3k × (-2) = 6

6 - 6k = 6

6k = 6 - 6

6k = 0

k = 0/6

➡k = 0

Hence

Value of k be = 0

Answer 2

Complete Question :

›»› 5x + 3y = 9 and 2x - 3y = 12 find the value of x and y = ?

⠀ ⠀ ⠀ ━━━━━━━━━━━━━━━━⠀

Given :

• 5x + 3y = 9
• 2x - 3y = 12

To Find :

• The value of x and y = ?

Required Solution :

In the above Question, we have to find the value of x and y So, firstly we have to Both given elements have to be considered as equation 1 and equation 2. And then we have to add equation 1 and 2 Then, we can frame equation to get the result of x and y$.$

5x + 3y = 9 .....(1)

2x - 3y = 12 .....(2)

So let's start solving the equation and understand the steps to get our final result for x. and y.

Adding equation (1) and (2)

⇛ 5x + 2x = 9 + 12

⇛ 7x = 9 + 12

⇛ 7x = 21

⇛ x + 21/7

⇛ x = 3

Put the value of x in equation (2)

⇛ 2x - 3y = 12

⇛ 2 × 3 - 3y = 12

⇛ 6 - 3y = 12

⇛ 3y = 6 - 12

⇛ 3y = -6

⇛ y = -6/3

⇛ y = -2

║Hence, the value of x is 3 and the value of y is -2.║
