Question

Please help me the blue line is what I have to solve for

Answer 1

We have the following:

`b-4-2p+5=6p+1`

solving for b (blue line):

`\begin{gathered} b-4-2p+5=6p+1\text{ } \\ \text{ We group similar terms} \\ b-4+5-1-2p+2p=6p+1-1+2p \\ b+(-4+5-1)=(6p+2p) \\ \text{ we reduce similar terms} \\ b=8p \end{gathered}`

Therefore, the answer is:

`8p-4-2p+5=6p+1`
