Answer:

$7=x$

Step-by-step explanation:

Equation

$4x = 7(x - 3)$

we apply distributive property $c(b+a)= bc+ac$

$4x = 7x - 21$

Group similar terms

$21=7x-4x$

Resolve addition / subtraction operations

$21=3x$

clear the x. Dividing both terms by the coefficient that accompanies the x

$\frac{21}{3}=\frac{3x}{3}$

$7=x$
