Answer 1

1)-83х+21у
2)20а-15b
3)1/16c-2,1d
4)-3/10t-1,12

Answer 2

1) -66х + 20у - 17х + у

To find the like terms in the expression -66х + 20у - 17х + у, we need to identify the terms that have the same variables raised to the same powers.

The like terms in the given expression are: -66х and -17х (both have the variable х) 20у and у (both have the variable у)

Therefore, the like terms in the expression are -66х, -17х, 20у, and у.

2) 8.2а - 9b + 11.8а - 6b

To find the like terms in the expression 8.2а - 9b + 11.8а - 6b, we need to identify the terms that have the same variables raised to the same powers.

The like terms in the given expression are: 8.2а and 11.8а (both have the variable а) -9b and -6b (both have the variable b)

Therefore, the like terms in the expression are 8.2а, 11.8а, -9b, and -6b.

3) 3/16c + 7.3d - 1/8c - 9.4d

To find the like terms in the expression 3/16c + 7.3d - 1/8c - 9.4d, we need to identify the terms that have the same variables raised to the same powers.

The like terms in the given expression are: 3/16c and -1/8c (both have the variable c) 7.3d and -9.4d (both have the variable d)

Therefore, the like terms in the expression are 3/16c, -1/8c, 7.3d, and -9.4d.

4) 6 целых 1/5t - 20.15 + 19.03 - 7 целых 1/2t

To find the like terms in the expression 6 целых 1/5t - 20.15 + 19.03 - 7 целых 1/2t, we need to identify the terms that have the same variables raised to the same powers.

The like terms in the given expression are: 6 целых 1/5t and -7 целых 1/2t (both have the variable t)

Therefore, the like terms in the expression are 6 целых 1/5t and -7 целых 1/2t.

I hope this helps! Let me know if you have any further questions.
