Let x= -2, y=4, and z =1/2 evaluate z(y-3x)+x

The answer is 3.

Step-by-step explanation:

1. You need to substitute the values into the equation

2. You would then have 1/2(4-3(-2))-2

3. Now you have to multiply 3×-2 and you will now have 1/2(4+6)-2

4. Then you have to add what's in the parenthesis and you will have 1/2(10)-2

5. Now multiply 1/2(10) and uou will have 5-2

6. Now subtract 5-2 and that will = 3

0 is its x and y coordinate
