+11912 So in this we will in the both parts multiply then two things like in the first one we will multiply 2 by 5x and -2y and so this same rule applies in the second part too!
So we shall do this like!
2(5x-2y)+5(5x-3y)
(Now we will multiply 2 by 5x and -2y and also 5 with 5x and -3y)
=10x – 4y + 25x – 15y
(now we will place them in the correct places)
=10x + 25x – 4y – 15y
(now simply so as the signs say)
=35x – 19y ANSWER
i hop ths helps and if you still havent understood , please ask freely!
