Question

use the distributive property to solve the equation.
$4.2 = \frac{3}{5}(b - 2)$
the solution is $\boldsymbol{\square}$. (type the value of $b$.)

Explanation:

Step1: Apply Distributive Property

$4.2 = \frac{3}{5}b - \frac{3}{5} \times 2$
$4.2 = 0.6b - 1.2$

Step2: Isolate variable term

$0.6b = 4.2 + 1.2$
$0.6b = 5.4$

Step3: Solve for $b$

$b = \frac{5.4}{0.6}$
