solve the following equation: -
6+5 (a-1) = 30

29/5 or 5.8

Step-by-step explanation:

6+5(a−1)=30

first it would be good to distribute:

6+5(a-1)=30 -> 6+(5)(a)+(5)(−1)=30 which simplifies to 6+5a+−5=30

at this point it is best to rearrange:

(5a)+(6+−5)=30 which simplifies to 5a+1=30

from then on its a matter of doing opposite operation. at my school we would call this the "equality" method. what you do to one side you do the other.

Observe:

5a+1=30

    -1   -1

5a=29

5a/5=29/5

a=29/5 (in decimal it would be like 5.8)

I hope this is helpful!
