Question

Answer two questions about Equations A and B:A. 2x-1=5xB -1=3x1) How can we get Equation B from Equation A?

Answer 1

The Solution.

Step 1:

We shall write out the two equations.

`\begin{gathered} 2x-1=5x\ldots\text{eqn(A)} \\ -1=3x\ldots eqn(B) \end{gathered}`

Step 2:

We shall subtract 2x from both sides of equation A to obtain equation B.

`\begin{gathered} 2x-1=5x \\ \text{Subtracting 2x from both sides, we get} \\ 2x-1-2x=5x-2x \\ -1=3x\text{ (equation B)} \end{gathered}`
