Answer:

-3y - 4 + 2x

Step-by-step explanation:

when it says combine like terms, it means combine the terms that have the same variable

-7y, -2y, and 6y all have the same variable: y

so when you combine them, you get -3y (notice that the variable doesn't change, only the number in front of it does)

-2 and -2 are like terms, they don't have a variable

when you combine them, you get -4

-4x and 6x are like terms, their common variable is x

when you combine these, you get 2x

now put your answers together to get -3y - 4 + 2x

2x° + 1 + x° - 6 + 59°= 360°

3x° + 54° = 360°

3x = 306°

x = 102°

2(102°) + 1°= 204° + 1° = 205°

102° - 6°= 96°

205° + 96° + 59°= 360°
