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
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
