9- 4b = 3 + 8b how do you solve this?

Have all the terms containing the variable on one side of the equation and the rest of the terms on the other side of the equation.

I will put all terms containing the variable b on the left side of the equation and the rest on the right side of the equation.

Subtract 8b from both sides of the equation.

-9 -12b = 3

Add 9 to both sides of the equation to isolate the term with the variable b.

-12b = 12

Divide both sides of the equation by -12 to solve for b.

b = -1
