Question

5x + y = 720x + 2 = y

Answer 1

We can solve this system of the linear equation as follows:

Substituting the value of x = 1/5 in the next equation, we have the value for y:

`5\cdot((1)/(5))+y=7\Rightarrow1+y=7\Rightarrow y=7-1\Rightarrow y=6`

Then, we have that the solutions for this system are x = 1/5 and y = 6.
