Answer:

x=40

Explanation:

First take the smaller x value 1/2x and subtract it from the other side

(you can simplify the fractions into decimals by divide the top from the bottom.)

0.75(3/4)

0.50 (1.2)

0.75- 0.50=0.25

so now you have this equation because you replace both x's with one (the new x is the difference between the x's.)

0.25-2=8

Then even out the sides to get x alone with the answer. You do this by reversing the action of the regular number. In this case its -2 so add 2 to the 8.

8+2=10

then the new equation is:

0.25x=10

so now divide the answer by the x value

10/0.25=40

Its a large number because you are dividing by a decimal.

So x=40
