Hi I really need help with this question and I don't know a thing about algebra!!! If anyone can help me understand this that would mean a lot! So here's my question.
Brad says that the literal equation a = 3b + 4c - a is solved for a. Do you agree? Why or why not?
Once a is all by itself, expressed in terms of the other values, the equation has been solved for a.
That is not the case here, since a occurs on both sides of the equation.
Brad says that the literal equation a=3b+4c-s is solved for a. Do you agree?ehy or why not
To determine whether the given equation a = 3b + 4c - a is solved for a, we need to simplify and rearrange the equation to isolate the variable a.
Let's go step-by-step:
Step 1: Combine like terms on the right side of the equation.
a = 3b + 4c - a
Rearranging the terms:
a + a = 3b + 4c
Simplifying:
2a = 3b + 4c
Step 2: Divide both sides of the equation by 2 to isolate a.
2a/2 = (3b + 4c)/2
Simplifying:
a = (3/2)b + 2c
Therefore, the equation a = 3b + 4c - a is not correctly solved for a. The correct solution for a is a = (3/2)b + 2c.
To determine if the literal equation a = 3b + 4c - a is solved for a, we can simplify the equation by isolating the term that represents 'a' on one side of the equation.
First, let's group the 'a' terms together:
a + a = 3b + 4c
Now, combine the 'a' terms:
2a = 3b + 4c
Finally, divide both sides of the equation by 2 to isolate 'a':
a = (3b + 4c) / 2
Now we have solved the equation for 'a'.
The expression (3b + 4c) / 2 represents the value of 'a' in terms of 'b' and 'c'.
Therefore, Brad is incorrect. The correct solution for the literal equation a = 3b + 4c - a is a = (3b + 4c) / 2.
