Answer:
x=2
Step-by-step explanation:
We need to find the value of x when y is equal to -4
So, if we replace y by -4 on the initial equation, we get:
y = -3x + 2
-4 = -3x + 2
So, subtracting 2 on both sides of the equation:
-4 - 2 = -3x + 2 - 2
-6 = -3x
Dividing by -3, we get:

Therefore, the missing value is x = 2
