Solve for x . 11/4x+9=31

1 answer

To solve the equation 11/4x + 9 = 31, we'll first subtract 9 from both sides:

11/4x + 9 - 9 = 31 - 9

This simplifies to:

11/4x = 22

Next, we'll multiply both sides by the reciprocal of 11/4, which is 4/11:

(4/11)(11/4x) = (4/11)(22)

The left side simplifies to:

x = 88/11

Therefore, x = 8.
