Question

Help me please 15 pts
3a + 5 = a- 3

Answer 1

Hello!

Answer:

a=-4

*The answer must have a negative sign.*

Explanation:

Distributive property: a(b+c)=ab+ac

First, you subtract by 5 from both sides of an equation.

`3a+5-5=a-3-5`

Then, simplify.

`3a=a-8`

Next, you subtract by a from both sides of an equation.

`3a-a=a-8-a`

Simplify.

`2a=-8`

Then you can also divide by 2 from both sides of an equation.

`(2a)/(2)=(-8)/(2)`

And finally, simplify and solve. You can also divide by the numbers.

`8/2=4`

`a=-4`

Hope this helps!

Thanks!
