Answer:
Step-by-step explanation:
To solve this problem, you have to combine like terms of x and b from one side of the equation.
<h3>4x+3(2x+5b)-4b-2x+6</h3><u>Combine like terms.</u>
3(2x+5b)+4x-2x-4b+6
<u>Solve.</u>
4x-2x=2x
Rewrite the problem down.
3(2x+5b)+2x-4b+6
Expand the form.
Use a distributive property.
<u>Distributive property:</u>
A(B+C)=AB+AC
3(2x+5b)
<u>Multiply.</u>
3*2x=6x
3*5b=15b
<u>Rewrite the problem.</u>
6x+15b
6x+15b+2x-4b+6
<u>Combine like terms.</u>
6x+2x+15b-4b+6
<u>Add the numbers from left to right.</u>
6x+2x=8x
8x+15b-4b+6
<u>Then, you add again.</u>
15b-4b=11b
<u>= 8x+11b+6</u>
- <u>Therefore, the final answer is 8x+11b+6.</u>
