Answer:

x = 3/4

y = 0

Explanation:

-3/2 = -1.5

To solve the system by elimination, we will add the two equations together when the y-coefficients have opposite signs.

We have:

```

4x-2y=3

y-2x=-1.5

```

Adding the two equations together, we get:

```

2x=1.5

```

Dividing both sides by 2, we get:

```

x=0.75

```

Substituting this value of x into the top equation, we get:

```

4*0.75-2y=3

```

```

3-2y=3

```

```

-2y=0

```

```

y=0

```

Therefore, the solution to the system is x=0.75 and y=0.

**Step-by-step work:**

1. Add the two equations together when the y-coefficients have opposite signs.

2. Solve for x.

3. Substitute the value of x into one of the original equations to solve for y.

4. Check your answer by substituting the values of x and y into both original equations.

**Answer:**

x=0.75

y=0
