0.79%289x%2B9%29%3E=2.2-1%28x%2B3%29 Start with the given inequality.


7.11x%2B7.11%3E=2.2-1x-3 Distribute.


100%287.11x%2B7.11%29%3E=100%282.2-1x-3%29 Multiply both sides by 100 to clear out the decimals.


711x%2B711%3E=220-100x-300 Distribute and multiply.


711x%2B711%3E=-100x-80 Combine like terms on the right side.


711x%3E=-100x-80-711 Subtract 711 from both sides.


711x%2B100x%3E=-80-711 Add 100x to both sides.


811x%3E=-80-711 Combine like terms on the left side.


811x%3E=-791 Combine like terms on the right side.


x%3E=%28-791%29%2F%28811%29 Divide both sides by 811 to isolate x.
