Question

When solving the following system of equations, which variable would be the easiest to solve for? {x+6y=25{2x+2y=9 A) the x in the first equationB)the y in the second equationC) the y in the first equationD) the x in the second equation

Answer 1

From the first equation, we have

`\begin{gathered} x+6y=25 \\ we\text{ can easily solve for x by subtracting 6y from both sides, we have } \\ x+6y-6y=25-6y \\ x=25-6y \end{gathered}`

So we can easily solve for x in the first equation.

Hence the answer is option A
