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
