Respuesta :
Adding 15 to both sides. In order to get it to the opposite side of the equal sign, you must do its opposite. You can't add 8x to both sides, because the opposite of positive 8x is negative 8x and that's not what they're asking. The opposite of negative 15 is positive 15, so it works. Opposite of positive 3 is negative three, and they're wanting a positive, so it will not work. Adding 2x wouldn't work, because it's already positive..
Answer:
adding 15 to both sides of the equation
Step-by-step explanation:
Find the possible first step in solving the equation [tex]8x+3 = 2x - 15[/tex]
To eliminate any variable or constant we always do opposite operation
adding 8x to both sides of the equation : Opposite of 8x is -8x, Subtract -8x to remove 8x
adding 15 to both sides of the equation: opposite of -15 is +15 so we add 15 on both sides
adding 3 to both sides of the equation: opposite of 3 is -3, so subtract 3 on both sides
adding 2x to both sides of the equation: opposite of 2x is -2x, so we subtract 2x on both sides
