Question

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

Answer 1

Answer:

value of x is 9/5-3y/5 and 6+3y/2

Answer 2

Solution

Given :-

• 5x + 3y = 9 --------(1)
• 2x - 3y = 12 -------(2)

Find :-

• Value of x & y

Explanation

Add equ(1) & equ(2)

==> 5x + 2x = 9 + 12

==> 7x = 21

==> x = 21/7

==> x = 3

Keep value of x in equ(2)

==> 2 * 3 - 3y = 12

==> 3y = 6 - 12

==> y = -6/3

==> y = -2

Hence

• Value of x = 3
• Value of y = -2
