Answer:

x=2/5 x=0.4

Step-by-step explanation:

Reorder the terms in parentheses

14+(-30x+54)=7*(10x+4)

Remove unnecessary parentheses

+14-30x+54=+7+*(+10x+4+)

Reorder the terms in parentheses

14-30x+54=+(+70x+28)

Remove unnecessary parentheses

+14-30x+54=+70x+28

We move all terms containing x to the left and all other terms to the right.

-30x-70x=+28-14-54

We simplify left and right side of the equation.

-100x=-40

We divide both sides of the equation by -100 to get x.

x=0.4
