Isolating Variables in Equations

The video tutorial explains how to solve for specific variables in different equations. It covers isolating variables by using operations such as division and subtraction. The tutorial demonstrates solving for P in I = PRT, Y in 11x + 2y = 6, C in a = b(C + d), and T in a = p + PRT. It emphasizes that equations can be expressed in multiple forms and provides step-by-step guidance for each example.

What is the expression for 'y' after isolating it in 11x + 2y = 6?

• y = 6 + 11x

• y = 6 / 11x

• y = 11x / 6

• y = (6 - 11x) / 2
