    Answer:

    b= 29/11

    Step-by-step explanation:

    2b+8−5b+3=−13+8b−5

    Step 1: Simplify both sides of the equation.

    2b+8−5b+3=−13+8b−5

    2b+8+−5b+3=−13+8b+−5

    (2b+−5b)+(8+3)=(8b)+(−13+−5)(Combine Like Terms)

    −3b+11=8b+−18

    −3b+11=8b−18

    Step 2: Subtract 8b from both sides.

    −3b+11−8b=8b−18−8b

    −11b+11=−18

    Step 3: Subtract 11 from both sides.

    −11b+11−11=−18−11

    −11b=−29

    Step 4: Divide both sides by -11.

    −11b/−11 = −29/−11

    b= 29/11
