5x + y = 5 .... Eq.1 we can write it in another way ... y = 5 - 5x
3x + 2y = 3 .... Eq.2
Put the value of Y in Eq.2
3x + 2(5 - 5x) = 3
3x + 10 - 10x = 3
3x - 10x = 3 - 10
- 7x = -7
x = -7/-7 ............. X = 1
to find the value of y, put the value of x in Eq.1
y= 5 - 5x
y= 5 - 5(1)
y= 5 - 5 ............. Y = Zero
