Question

Y=8x-11
Y=x-17
Solve the system of equations

Answer 1

`x=-(6)/(7)`

`y=-17(6)/(7)`

Explanation:

We are given the following system of equations that we are to solve:

`y = 8 x - 1 1` - (1)

`y = x - 1 7` - (2)

Since the left hand side of both the equations is the same so we will equate the right hand sides of both the equations to get:

`8x-11=x-17`

`8x-x=-17+11`

`7x=-6`

`x=-(6)/(7)`

Substituting this value of
`x` in (1) to find
`y`:

`y=8(-(6)/(7))-11`

`y=-17(6)/(7)`
