7(3b-1)=2b-26 please help and give me step by step ☺️​

b = -1

Step-by-step explanation:

7(3b-1): 7 goes into the numbers by multiplying. This will give you 21b-7.

So now the equation should be like 21b-7=2b-26.

-7 and 2b swap places, making 21b-2b=7-26. It will give you 19b= -19.

Finally divide the two numbers (-19 / 19) and the solution will be b= -1.

If I didn't make a clear answer or a good explanation, please comment. I sometimes mess up my steps, and this is my first time using this.

b = -1

Step-by-step explanation:

7(3b -1 ) = 2b - 26

First, distribute.

21b - 7 = 2b - 26

Then, add 7 to both sides AND subtract 2b on both sides

21b - 7 + 7 - 2b = 2b - 2b - 26 + 7

Add common terms

19b = -19

Divide by 19

b = -1

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
