Solve the following equation for A : 2A/3 = 8 + 4A

Sha:

2A/3 = 8 + 4A

~ The first step is to get rid of the denominator on the left side of the equation. We can do this by multiplying everything on both sides of the equation by 3. ~

2A = 3(8 + 4A)
2A = 24 + 4A

~ Now we must combine like terms. Remember that in order for two terms to be considered alike, they must fulfill two requirements: same power, same variale. ~

-2A = 24
A = -12

FINAL ANSWER: -12

Sha:

typo: variale--variable

Sha:

Oops! HUGE mistake! I forgot to multiply 4A by 3...please overlook everything I wrote after my first 3 sentences and look at this instead:

2A = 3(8 + 4A)
2A = 24 + 12A

~ Now we must combine like terms. Remember that in order for two terms to be considered alike, they must fulfill two requirements: same power, same variable. ~

-10A = 24
A = -12/5 OR -2.4

FINAL ANSWER: -12/5 OR -2.4

:)

Pingy:

Is this for school how old are you

Pamela:
i am 59 yrs old how did you get -10A=24 i undrestand that you multipied 3x8 & 3x4 but how did you get  -10A
Amanda Couch:
You have to minus the 12A from both sides to get rid of the A on the right side. If you minus 12A from 2A, you get -10A.
