Step 1a

Rewrite the equation.

Explanation: Rewrite the equation.

\$((6b)/3 + 3b)/2 = 1\$.

⇒ \$(6b)/3 + 3b = 1 times 2\$

⇒ \$(6b)/3 + 3b = 2\$

Step 1b

Perform operation according to PEMDAS rule.

Explanation: Perform operation according to PEMDAS rule.

⇒ \$(6b)/3 + 3b = 2\$

⇒ \$(6b + 9b)/3 = 2\$

⇒ \$(15b)/3 = 2\$

⇒ \$15b = 2 times 3\$

⇒ \$15b = 6\$

Step 1c

Apply division property.

Explanation: Divide both sides of the equation by 3.

⇒ \$(15b)/3 = 6/3\$

⇒ \$(cancel15^5b)/cancel3^1 = cancel6^2/cancel3^1\$

⇒ \$(5b)/1 = 2/1\$

⇒ \$5b = 2\$

Again divide both sides of the equation by 5.

⇒ \$(5b)/5 = 2/5\$

⇒ \$(cancel5^1b)/cancel5^1 = 2/5\$

⇒ \$b/1 = 2/5\$

⇒ \$b = 2/5\$
