Answer:
b=5
Step-by-step explanation:
So, they basically equal each other since they both equal a.
6b+20=4b+30
Your first step is to move the variable to one side, by that I mean to subtract. You have to subtract the smallest number that has a variable, in this case it would be 4b.
6b+20= 4b+30
-4b -4b
Once you have subtracted the variable, and now that there is only one variable in the equation, you have to subtract 20, since that is the opposite of adding.
2b+20=30
-20 -20
Then, you have to divide 2 from 10, since that is the opposite of multiplying.
<u>2b</u>=<u>10</u>
2 2
Conclusion- b=5
