Literal Equations Practice

Solving literal equations means you must use __________ to isolate a given variable.

• magic tricks

• apps that solve for you

• inverse operations

• Harry Potter

Solve for n :

3m + 5n = -40

Solve for y :

8x + 3y = 27

Solve for y :

8x - 6y = 84

•   y = -14

•   answer not here

Solve for c :

5(a + c) = 35

• c = a + 7

• c = 7 - a

• c = 35 - 5a

• c = 30 - a

What is the first step in isolating "y" in this equation?

6x + 11y = -154

• Divide -154 by 6

• Subtract 6x from both sides

• Divide -11 by 6

• Subtract 11y from both sides

Isolate W in the perimeter formula for a rectangle:

P = 2(L + W)

**SELECT TWO CORRECT FORMS OF THE ANSWER**

Solve for t :

d = rt

• t = d - r

• t = d/r

• t = dr

• answer not here

Solve for y:

3x - 8y = -40

• y = (3/8)x + 5

• y = (-3/8)x - 5

• y = (8/3)x + 5

• y = (-8/3)x - 5
