Question

What is the solution to the system of equations y equals 1.5 x - 4 y equals negative X

Answer 1

(1.6, -1.6)

Explanation:

We have the following system of equations:

`y=1.5x - 4`

`y=-x`

We have the following system of equations:

To solve the system substitute the second equation in the first one and solve for x

`y=1.5x - 4`

`-x=1.5x - 4`

`4=2.5x`

`2.5x =4`

`x =(4)/(2.5)`

`x = 1.6`

Now replace the value of x in one of the two equations and solve for y

`y=-x`

`y=-1.6`

The solution is:

(1.6, -1.6)
