Solve for x.
x = 6°
x = 15°
x = 30°
x = 90°

Step-by-step explanation:
Your question isn't complete.
But if you are asking for finding the value of variable then, you should follow these things
x+2=6
x+2-2=6-2
x=4
Hence, positive number is cancelled
x-3=1
x-3+3=1+3
x=1
Hence, negative number is cancelled
3x=6
3x/3=6/3
x=2
Hence, the number in product form is cancelled
y÷3=1
y÷3×3=1×3
y=3
Hence, the number in divide form is cancelled
