Solving Linear Equations Steps

The video tutorial demonstrates how to solve the equation -20 = -4x - 6 by isolating the variable x. It involves adding 6 to both sides to eliminate the constant term and then dividing by -4 to remove the coefficient of x, resulting in the solution x = 7/2.

What is the initial equation that needs to be solved?

• -20 = -4x - 6

• 20 = 4x + 6

• 20 = -4x - 6

• -20 = 4x + 6

What operation is performed to eliminate the constant term on the right side of the equation?

• Subtract 6 from both sides

• Divide both sides by 6

• Add 6 to both sides

• Multiply both sides by 6

After adding 6 to both sides, what does the equation become?

• 0 = -4x

• -14 = -4x

• 6 - 20 = -4x

• -20 = -4x + 6

What is the next step after obtaining -14 = -4x?

• Add 4 to both sides

• Multiply both sides by -4

• Divide both sides by -4

• Subtract 4 from both sides

What is the final value of x after solving the equation?

• x = 14

• x = 2

• x = 7/2

• x = 7
