$x = 12$ $x=12$

First, get rid of the denominator of $x$ $x$ by multiplying both sides of the equation by 5.

$5 \cdot (\frac{x}{5}) + 5 \cdot 6 = 5 \cdot 8.4$ $5*(x/5)+5*6=5*8.4$

$x + 30 = 42$ $x+30=42$

Subtract 30 from both sides to get the $x$ $x$ by itself.

$x + 30 - 30 = 42 - 30$ $x+30-30=42-30$

$x = 12$ $x=12$

How do you solve x5+6=8.4\frac { x } { 5} + 6= 8.4?
