#### Answer

This system has no solutions - it is inconsistent.

#### Work Step by Step

Follow the steps below:
Step 1: Add the 1st equation multiplied by $2$ to the second equation
$$2x+2(-x)-4y+2\times2y=3+2\times1.5$$ which gives $$0=6.$$
Since we know that in fact $0\neq6$ this system is inconsistent and has no solutions.
