Answer:

[tex]a= r- d - c[/tex]

Step-by-step explanation:

Converting the equation to solve for a really just means getting a alone on one side of the equation.

[tex]a + c = r - d[/tex]

To get a alone on the left, we can subtract c from both sides:

[tex]a+ c = r -d\\a = r - d - c[/tex] (Since c - c = 0, c will disappear from the left side.)

Answer: [tex]a= r- d - c[/tex]

Answer:

[tex] \longmapsto \: a + c = r - d \\ (a + c) - c = (r - d) - c \\ \boxed{a = r - d - c}✓[/tex]

  • a = (r - d - c) is the right answer.
