Somebody help me please thank you so much

I’m not really sure but my guess is x: -2,2 y: -4,4 z: 1,4 . I hope this helps! :)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
