Literal Equations Review

Front

Solve m - n = 5 for m.

Back

m = n + 5

Front

Solve: y = mx + b, for b.

Back

b = y - mx

Front

Solve I = prt for r.

Back

r = I / (pt)

Front

Solve for y: 5x + y = 16.

Back

y = -5x + 16

Front

Solve IR = V for R.

Back

R = V / I

Front

What is a literal equation?

Back

A literal equation is an equation that involves two or more variables.

Front

What does it mean to solve for a variable?

Back

Front

What is the first step in solving m - n = 5 for m?

Back

Add n to both sides of the equation.

Front

How do you isolate b in the equation y = mx + b?

Back

Subtract mx from both sides.

Front

What is the formula for calculating resistance in an electrical circuit?

Back

R = V / I, where R is resistance, V is voltage, and I is current.
