9b = 27. i need to find the value for b

b = -3

Step-by-step explanation: To solve for b in this equation, we want to get b by itself on the left side of the equation.

Since b is being multiplied by -9, to get b by itself, we need to divide by -9 on the left side of the equation. Since we divide by -9 on the left side, we must also divide by -9 on the right side.

On the left side, notice that the -9's cancel out so we are simply left with b. on the right side, we have 27 divided by -9 which is -3. So now we have b = -3.

Finally, remember yo check your answer by substituting a -3 back into the original equation. So we have -9 (-3) = 27 which is a true statement so our answer b = -3 is correct.

b= -3

Step-by-step explanation:

-9(-3)=27

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
