Step-by-step explanation:
no
a) 3x-2y - 3x-2y
because of the x and y thay are not same if thay are same than ti will 1x or 1y
b) 5x-3y-5x-3y
because of the x and y thay are not same if thay are same than ti will 2x or2y
Step-by-step explanation:
sol:
3x - 2y = 5 ——— 1
5x - 3y = 13 ———2
From 1
3x - 2y = 5
=) 3x = 5 + 2y
=) x = 5 + 2y/3 ——— 3
substituting equation 3 in 2
5x - 3y = 13
=) 5(5+2y/3) - 3y = 13
=) 25+10y/3 - 3y = 13
=) 25+10y - 9y/3 = 13
=) 25+y = 39
=) y = 39 - 25
=) y = 14
Substituting y = 14 in equation 3
=) x = 5+2(14)/3
=) x = 5+28/3
=) x = 33/3
=) x = 11
