x=34

Explanation:

Whenever you see an equation like this the first thing you want to do is get all of the x terms on one side and all of the constants on the other.

1.5x+2-1.2x=12.2

1.5x-1.2x=12.2-2

Now we can combine the terms because they are all common

0.3x=10.2

Now we divide both sides by 0.3 to find the value of x

(cancel0.3x)/cancel0.3=10.2/0.3

x=10.2/0.3

color(blue)(x=34)

We can even check our answer by putting our value for x into the original equation.

1.5x+2-1.2x=12.2

1.5(color(blue)(34))+2-1.2(color(blue)34)=12.2

51+2-40.8=12.2

53-40.8=12.2

color(green)(12.2=12.2)
