Answer:

x = -1

Step-by-step explanation:

Well we know the equation -4x + 7 = 11

To solve this we will first subtract 7 from both sides

-4x + 7 = 11

-4x = 4

Next, we will divide both sides by the coefficient, -4, to isolate the variable, x

-4x = 4

x = -1

This will result in our answer of x = -1
