Mathematics

The first step is Add 6 to both sides

Step-by-step explanation:

we have

$\frac{2}{5}x-6=-16$

Solve for x

That means ----> isolate the variable x

step 1

Adds 6 both sides

$\frac{2}{5}x-6+6=-16+6$

$\frac{2}{5}x=-10$

step 2

Multiply by 5/2 both sides

$\frac{2}{5}x(\frac{5}{2})=-10(\frac{5}{2})$

x=-25

therefore

The first step is Add 6 to both sides
