Answer:
y=97
Step-by-step explanation:
1st do 42+55=97 to find
2nd do 180-97=83 to find z so z=83
3rd do then do 180-83=97 sense y and z are supplementary
so therefore the answer is y=97
If brainiest is earned its greatly appreciated
Expand
(4a + 12 = 12 + 4a)
Cancel 4a on both sides
12 = 12
Since both sides are equal there are infinitely many solutions
Process of elimination, cross out d) no solution. But I would best go with C)
