Solve.
zvonat [6]

Answer:

x

Step-by-step explanation:

<u><em>The correct question is</em></u>

Solve. −3/5x+1/5>7/20 Drag and drop a number or symbol into each box to show the solution

we have

-\frac{3}{5}x+\frac{1}{5} >\frac{7}{20}

Solve for x

Multiply by 20 both sides

-12x+4 >7

subtract 4 both sides

-12x >7-4

-12x >3

divide by -12 both sides

Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

x

simplify

x
