GCSE Secondary Maths Age 13-17 - Algebra: Algebra - Problem - Explained

The video tutorial explains how to make T the subject of the formula y = T/3 - 2A. It begins by identifying whether T is in one or two places in the equation. Since T is in one place, the process is straightforward. The tutorial demonstrates adding 2A to both sides and then multiplying by 3 to isolate T, resulting in the formula T = 3(y + 2A). The video also discusses the marking scheme, highlighting that expanding the brackets is unnecessary for extra marks.

What is the first step to isolate T in the equation y = T / 3 - 2A?

Explain how you would multiply both sides of the equation to isolate T.

What is the final expression for T after isolating it?

Why is it unnecessary to expand the brackets in the final answer?

What marks are awarded for the process of isolating T?
