-9b+8=-3+3(b-5) what is the answer to this problem

Hello there, to answer your question...

Let's solve your equation step-by-step.

−9b+8=−3+3(b−5)

Step 1: Simplify both sides of the equation.

−9b+8=−3+3(b−5)

−9b+8=−3+(3)(b)+(3)(−5)(Distribute)

−9b+8=−3+3b+−15

−9b+8=(3b)+(−3+−15)(Combine Like Terms)

−9b+8=3b+−18

−9b+8=3b−18

Step 2: Subtract 3b from both sides.

−9b+8−3b=3b−18−3b

−12b+8=−18

Step 3: Subtract 8 from both sides.

−12b+8−8=−18−8

−12b=−26

Step 4: Divide both sides by -12.

−12b/−12

=

−26/−12

b=
