Can somebody please give me the answer I will mark u brilliant

Answer 1

Answer:

x = 6.7

Step-by-step explanation:

We know that 3.5 + x = 10.2, so if we do inverse operations we can find out the value of x.

10.2 - 3.5 = 6.7

we can check our work by substituing it back in the equation for x

6.7 + 3.5 = 10.2

so now we know that x = 6.7. I hope this helps :)

Answer 2

Answer: x=6.7

Step-by-step explanation:

x+3.5=10.2

-3.5    -3.5
