How to do this equation by elimination 8x +14y= 4 and -6 + -7y =-10

8x + 14y = 4
-6x - 7y=-10  / *2

8x + 14y=4
-12x -14y= -20

-4x=-16 => x=4; y= -2

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!
