b) 4,5x – 2,8y – 1,9x – 2,6y =
c) 10,7x – 4,8 + 0,8y – 5,2x – 8,8y =
answers: combining like terms exercise 2
a) 0,5x – 3,2x + 0,9x = 1,8x
in detail:
0,5x – 3,2x + 0,9x = – 1,8x
b) 4,5 x – 2,8y – 1,9x – 2,6y = + 2,6x – 5,4y
in detail:
+ 4,5x – 1,9x = + 2,6x
– 2,8y – 2,6y = – 5,4y
c) 10,7x – 4,8 + 0,8y – 5,2x – 8,8y = + 5,5x – 8y – 4,8
in detail:
+ 10,7x – 5,2x = + 5,5x
+ 0,8y – 8,8y = – 8y
– 4,8 = – 4,8
