Solve for x.

78.2 + 0.5x = 287

417.6

Step-by-step explanation:

In order to solve for x, you have to get x by itself.

78.2 + 0.5x = 287 (First, you subtract 78.2 on both sides)

-78.2 - 78.2

0.5x/0.5 = 208.8/0.5 (now, you divide both side by 0.5)

Leaving with,

x = 417.6

so, x equals to 417.6

Step-by-step explanation:

0.5x=208.8

x=417.6
