# Substitute values into formulas to determine an unknown and re-arrange formulas to solve for a particular term (VCMNA333)

[/fusion_text][fusion_text]LO: To rearrange formulas to solve for a particular term

Know:

• What is a term
• What is a formula
• How to rearrange formulas to isolate a particular term
• Inverse operations

Understand:

• That formulas can be rearranged to isolate a particular term

Do:

• I can rearrange formulas to isolate a particular term

# What is a Formula?

### A formula always has more than one variable.

# What is the subject of the formula?

[/fusion_text][/one_full][one_half last=”yes” spacing=”yes” center_content=”no” hide_on_mobile=”no” background_color=”” background_image=”” background_repeat=”no-repeat” background_position=”left top” border_position=”all” border_size=”0px” border_color=”” border_style=”” padding=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”” animation_speed=”0.1″ class=”” id=””][imageframe lightbox=”no” lightbox_image=”” style_type=”none” hover_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”none” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ hide_on_mobile=”no” class=”” id=””] [/imageframe][fusion_text]

### In this case, “v” is the subject of the formula because it is isolated from the rest of the variable.

### This question wants you to make “e” the subject rather than m.

### That’s how you can isolate the subject by rearranging formulas.
