Step-by-step explanation:
Given:
3x + 2y - 6
5x - 4y + 2
Solution:
( sending variables to other side changes their signs)
3x +2y = 6 ---> eq1
5x - 4y = -2----> eq2
multiplying eq1 with 2
2( 3x + 2y = 6)
6x +4y = 12---> eq3
Adding eq 1 and eq 3
6x +4y = 12
+ 5x - 4y = -2 ( +4y and -4y gets cancelled)
x = 10
Putting x= 10 in eq 1
3x +2y = 6
3* 10 + 2y = 6
30 +2y = 6
2y= 6-30
y= -24/2
y = -12
Therefore,
y = -12
x = 10
