2x + 5y = 2 ..... Eq.1
-3x - y = -3 ..... Eq.2 .... we can write it in another form y = 3 - 3x
Put the value of y in Eq.1 the result will be :
2x + 5(3 - 3x) = 2
2x + 15 - 15x = 2
2x - 15x + 15 = 2
-13x + 15 = 2
-13x = 2 - 15
-13x = -13
x = -13/-13 ......... X = 1
to find Y, put the value of X in Eq.2
y = 3 - 3x
y = 3 - 3(1)
y = 3 - 3 .......... Y = Zero
