Hello!
To solve an algebraic equation, you must isolate the variable on one side. We’ll begin by restating the given equation:
12 + 12n = -48
Now subtract 12 from both sides of the equation:
12n = -60
Divide both sides by 12:
n = -5
We have now proven that “n” is equal to (-5).
I hope this helps!
Aaron is 4 years and Maria is 14 years old.
A = Aaron's age today
M = Maria's age today.
a. The equation based on the statement given will be:
M = A + 10
b. Maria's age based on the statement in 6 years will be:
= (A + 10) + 6
= A + 16
c. Based on the information above, the equation to solve their ages will be:
A + 16 = 2(A + 6)
A + 16 = 2A + 12
Collect like terms
2A - A = 16 - 12
A = 4
Therefore, Aaron is 4 and Maria is 14 years.
