Answer 1

Answer:

Finally, the value of A is 40.

Answer 2

Answer:

Finally, the value of A is 40.

Step-by-step explanation:

To solve this problem, first you have to isolate by the value of a from both sides of the equation.

First, group like terms. (combine like terms)

3a+2a+5-25=180

Add numbers from left to right.

3a+2a=5a

5a+5-25=180

Next, add & subtract numbers from left to right.

5-25=-20

5a-20=180

Also, add 20 from both sides.

5a-20+20=180+20

Solve.

180+20=200

5a=200

Then, divide by 5 from both sides.

5a/5=200/5

Last but not least, solve.

200/5=40

Finally, the value of A is 40.
