Step 2: Add 7 to each side to isolate the x terms:
![\[8 = 0.8x\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ot5v57wri50rmtsf7h7hu4vvsfrwh0ply8.png)
Step 3: Divide each side by 0.8 to solve for
:
![\[x = (8)/(0.8)\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/qpre1oyztlyhos9fygfh2axjmtii2c7kzh.png)
