Let's solve your equation step-by-step.

4.22549x−0.845098=0.845098x+5.915686

Step 1: Subtract 0.845098x from both sides.

4.22549x−0.845098−0.845098x=0.845098x+5.915686−0.845098x

3.380392x−0.845098=5.915686

Step 2: Add 0.845098 to both sides.

3.380392x−0.845098+0.845098=5.915686+0.845098

3.380392x=6.760784
