Question

-3a + 5 =-1 please help me

Answer 1

Answer:

2

Step-by-step explanation:

To find a we need to first isolate it. There is a 5 on the left side along with the -3a that has to be moved.

To do this, we can subtract 5 from both sides of the equation using the subtraction property of equality.

-3a + 5 - 5 = - 1 - 5

-3a = -6

Now that the a term is isolated, the next step is to remove the coefficient.

Let's use the division property of equality and divide both sides of the equation by -3.

-3a/-3 = -6/-3

a = 2

Answer 2

Answer:

2

Step-by-step explanation:

-3a + 5 = -1

5+1 =3a

6 =3a

divide both sides by 3

6/3 = 3a/3

2=a

Therefore a=2
