Answer: [tex]b=1[/tex]
Step-by-step explanation:
Given the equation [tex]-3(-8b+7)=3(2b-1)[/tex] you need to solve for the variable "b".
You need to apply Distributive property on both sides of the equation:
[tex]-3(-8b+7)=3(2b-1)\\\\24b-21=6b-3[/tex]
Now you need to add 21 to both sides of the equation:
[tex]24b-21+21=6b-3+21\\\\24b=6b+18[/tex]
Subtract [tex]6b[/tex] from both sides:
[tex]24b-6b=6b+18-6b\\\\18b=18[/tex]
And finally, you can divide both sides of the equation by 18:
[tex]\frac{18b}{18}=\frac{18}{18}\\\\b=1[/tex]
Answer:
b=1
Step-by-step explanation:
You first need to multiply -3 and -8b. That will be 24b. Then you multiply -3 times 7. That will be -21. On the other side, you will multiply 3 times 2b which will equal 6b. Then you multiply 3 by -1. You will get -3. So at this point, the equation should look like this, 24b-21=6b-3. Then add 21 to both sides. You will have this equation, 24b=6b+18. Then subtract 6b from both sides, 18b=18. Finally, divide 18 from both sides to get your final answer of b=1.
