Solving an equation for y and x using two steps

The video tutorial explains how to solve literal equations for variables X and Y. It begins with an introduction to the concept and its relevance in graphing and solving systems. The instructor demonstrates the process of solving for X by undoing addition and division operations. Similarly, the steps to solve for Y are shown, emphasizing the importance of rearranging terms and dividing to isolate the variable.

What is the primary goal when solving a literal equation for a variable?

• To make the variable equal to zero

• To convert the equation into a graph

• To isolate the variable on one side of the equation

• To eliminate all variables from the equation

When solving for X in the equation 3X + 4Y = 15, what is the first operation you should perform?

• Multiply both sides by 3

• Add 4Y to both sides

• Subtract 4Y from both sides

• Divide both sides by 3

After subtracting 4Y from both sides in the equation 3X + 4Y = 15, what is the next step to solve for X?

• Add 15 to both sides

• Divide both sides by 3

• Multiply both sides by 3

• Subtract 15 from both sides

In the process of solving for Y, what operation is used to eliminate the term 3X from the equation?

• Subtract 3X from both sides

• Divide both sides by 3

• Add 3X to both sides

• Multiply both sides by 3

What is the final step in solving for Y in the equation 4Y = 15 - 3X?

• Add 3X to both sides

• Multiply both sides by 4

• Divide both sides by 4

• Subtract 15 from both sides
