Question

(Combining Equations)What is the result of adding these two equations ? 5x - y = 6 -2x + y = 8

Answer 1

3x=14

Step-by-step explanation:

Given the two equations:

`\begin{gathered} 5x-y=6 \\ -2x+y=8​ \end{gathered}`

Adding the two equations gives:

`\begin{gathered} \lbrack5x+(-2x)\rbrack+\lbrack-y+y\rbrack=6+8 \\ \lbrack5x-2x\rbrack+0=14 \\ 3x=14 \end{gathered}`
