Answer:
a = 96
Step-by-step explanation:
a / 4 - 5 = 19
We are given an equation with multiple "signs."
Our goal is to get "a" isolated. We first should add 5 to each side. We then get:
a / 4 = 24
We then have to do the opposite of division by multiplying. We multiply 4 on each side (so that the a is isolated) and we then get 24 * 4 which is equal to 96! A is equal to 96.
TO CHECK ANSWER:
You will put your answer (96) into "a" for the original equation. We get 96 / 4 - 5 = 19. We then solve this. We need to use PEMDAS since we have multiple signs. PEMDAS has multiplication and division first, so we need to first divide 96 by 4. We get 24. We then subtract 24 by 5. 24 - 5 = 19. This gives us 19 = 19. 19 IS indeed equal to 19, so this means that our answer is true.
Hope this helps!
