Name: Period: Date: Topic: Solving Literal Equations Essential Question: Can equations that appear to be different be equivalent and how can you solve them? Using the formula Distance: Rate x Time or D=RT, we can solve the formula for R or T. Given: d = rt solve for r
The formula for area of rectangle is A = lw. Find the formula for l.
Solutions to last four slides: Solutions: • d = rt solve for r • A = lw solve for l • P = 2l + 2w Solve for w • 3d + 14 = 7e – 4d Solve for d • r = • l = • w = • d = e - 2
Answer Now 1) Solve 2x - 4y = 7 for xTo get x by itself, what is the first step? • Add 2x • Subtract 2x • Add 4y • Subtract 4y
Compare the following • Solve both for y
Answer Now 2) Solve for y.What is the first step? • Multiply by 3 • Divide by 3 • Add a • Subtract a
Answer Now 3) The formula for the volume of a rectangular prism is V = lwh. Which equation solves the formula for l? • L = V - WH
Don’t stress, it’s the same!Compare • Solve for d
Pair – Practice: • p + r = s Solve for r Solve for p • 4b – c = d Solve for b Solve for c • = 3j Solve for h
Convert 23° Fahrenheit to Degrees Celsius. • A formula is a type of literal equation because it contains constants and variables. 1 -5°C equals 23°F 1
Rewriting Literal Equations & Finding Values: 10x + 5y = 80 Solve for y Use re-written equation to find y when x = 3 and when x = 6
y + 2x = 5 Solve for y. Then find the value of y for each value of x: x = - 1 and x = 0
