Studdy Solution

STEP 1

Assumptions1. The equation is x−22=61−91x -22 =61 -91 . We are solving for xx

STEP 2

First, we simplify the right side of the equation.
61−91=−3061 -91 = -30So, the equation becomes2x−22=−302x -22 = -30

STEP 3

Next, we isolate the term with xx on one side of the equation by adding22 to both sides.
2x−22+22=−30+222x -22 +22 = -30 +22This simplifies to2x=−82x = -8

STEP 4

Finally, we solve for xx by dividing both sides of the equation by2.
x=−82x = \frac{-8}{2}

STEP 5

Calculate the value of xx.
x=−82=−4x = \frac{-8}{2} = -4So, the solution is x=−4x = -4.
