-1.2x + 11.45 = 8.21

kondaur [170]

Hi there!

If you solve for $x$ in this problem you would end up with a result of $\boxed{x = 2.7}$ . To find $x$ you need do the following:

First, subtract 11.45 from both sides:

$-1.2x+11.45-11.45=8.21-11.45$

$-1.2x=-3.24$

Next, divide both sides by -1.2:

$\frac{-1.2x}{-1.2} = \frac{-3.24}{-1.2}$

To get the end result of:

$\boxed{x = 2.7}$

Yes because you only need to look at the first decimal for problems like these and the first number you see a seven and a one and seven is greater than one
