(elimination using multiplication) 2x+y=0 5x+3y=2 show all work step by step

1. Set Up:
 -3(2x + y = 0)
   -6x -3y =-3
    5x+3y = 2 <2nd equation
     -1x=-1 <divide by -1
 > x = 1
2. Plug In:
 2(1) + y = 0
     2 + y = 0
    -2         -2
  > y = -2
3. Check
 2(1) + (-2) =0
> 2 - 2 =0

The length of what is left would be 1 1/2 feet long.

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!
