Solve for x . 11/4x+9=31 Responses x=22 x is equal to 22 - incorrect x=8 x is equal to 8 - not selected, this is the correct answer x=−8 x is equal to negative 8 - no response given x=110
To solve for x, we need to isolate the variable on one side of the equation.
Given the equation: 11/(4x+9) = 31
Multiplying both sides of the equation by (4x+9), we get:
11 = 31(4x+9)
Expanding the right side of the equation:
11 = 124x + 279
Subtracting 279 from both sides:
-268 = 124x
Dividing both sides by 124:
-2.161 = x
So, the correct answer is: x = -2.161
