Answer:

addition property of equality

Step-by-step explanation:

The addition property of equality is used to add 2x to both sides of the equation:

-2x +2x -3 = x +2x -18 . . step 2 with 2x added

-3 = 3x -18 . . . . . . . . . . . . step 3 (simplified)

Solve F=D+Drt for t.....

Anuta_ua [19.1K]

Answer:

$t = \frac{-D+F}{Dr}$

Step-by-step explanation:

Step 1: Flip the equation.

$Drt + D = F$

Step 2: Subtract D from both sides.

$Drt + D - D = F - D$
$Drt = -D + F$

Step 3: Divide both sides by Dr.

$\frac{Drt}{Dr} = \frac{-D+F}{Dr}$
$t = \frac{-D+F}{Dr}$
