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.
