Solving Equations with Fractions

The video tutorial explains how to solve the equation 12y + 7 = 1/8y by isolating the variable y. It discusses the decision to solve the equation with fractions intact and demonstrates the process of eliminating y terms from both sides. The tutorial covers finding a common denominator to combine y terms, isolating y by subtracting and dividing, and verifying the solution through substitution. The solution is confirmed to be correct by checking both sides of the equation.

What is the first step in solving the equation 12y + 7 = 1/8y?

• Multiply both sides by 8

• Isolate y on one side

• Add 7 to both sides

• Subtract 1/8y from both sides

Why might one choose to keep fractions in the equation rather than eliminate them?

• It simplifies the process

• It is a personal preference

• It makes the equation longer

• It avoids additional calculations
