How to solve a literal equation by eliminating a fraction e=1/2 Iw^2+u , I ex 23

The video tutorial explains how to solve a literal equation by isolating a variable. It begins by addressing the challenge of fractions in equations and demonstrates how to eliminate them by multiplying both sides by the denominator. The tutorial then simplifies the equation and rearranges terms to isolate the variable. Finally, it shows how to solve for the variable by undoing addition, subtraction, and division, resulting in the final equation.

What is the first step in solving the given literal equation for the variable I?

• Subtract W^2 from both sides

• Multiply both sides by 2

• Divide both sides by 1/2

• Add 2 to both sides

Why is it beneficial to eliminate fractions early in the equation-solving process?

• It makes the equation more complex

• It increases the number of variables

• It simplifies the equation and reduces confusion

• It makes the equation longer

After eliminating the fraction, what operation is performed to isolate the term with I?

• Subtract 2U from both sides

• Multiply by W^2

• Divide by 2

• Add 2U to both sides

What is the final operation needed to solve for I in the equation?

• Subtract E

• Divide by W^2

• Add W^2

• Multiply by 2

What is the final form of the equation for I?

• I = 2E + 2U / W^2

• I = 2E * 2U / W^2

• I = 2E - 2U * W^2

• I = 2E - 2U / W^2
