Question

What will the new equation 2 be whenmultiplying everything by-2?

Answer 1

In order to calculate the new equation, we just need to multiply every term in the equation by (-2). So we have that:

`\begin{gathered} (2a+3b=5)\cdot(-2) \\ 2a\cdot(-2)+3b\cdot(-2)=5\cdot(-2) \\ -4a-6b=-10 \end{gathered}`

So the answer is the first option.
