Answer:
186
Step-by-step explanation:
PEMDAS
First do 46 x 8 = 368 then divide that by 2, which would be, 184. Then add 2 to 184 and you get 186. :)
It’s a process of bringing one variable to the side with different forms of mathematical properties. First, subtract 2 from the left side and add it to the right side. Then divide 1/4x by 1/4 to get x alone, and divide the right side (-2) by 1/4, which will give you the answer to x. Let me know if you need help with anything else!
