Answers:
x=4 and y=27
x=8 and y=-1
x=1 and y=216
Step-by-step explanation:
You have to plug all of the choices given into the equation until it equals to 7
∛12 + 3 = 2.9 +3 = 5.29
∛27 + 4= 3 + 4 = 7
∛16 + 3 = 2.5 +3 = 5.5
∛-1 + 8 = -1 + 8= 7
∛216 + 1 = 6 + 1= 7
∛30 - 3 = 3.11 - 3 = 0.11
∛3 + 4 = 1.44 + 4= 5.44
