Another Tricky one here (Please not that my strong suit is not in math but in SS and history) Can anybody help me out cuz no joke I would really appreciate it!

x = -10

Step-by-step explanation:

Given the linear function, g(x) = -x + 3, and that g(x) = 13:

In this particular problem, it asks for you to find the input value that corresponds to an ouput value of 13.  

Substitute the output value into the function, and solve for the input (x-value):

g(x) = -x + 3

13 = -x + 3

Subtract 3 from both sides:

13 - 3 = -x + 3 - 3

10 = -x

Next, divide both sides by -1 to solve for x:

x = -10

Therefore, the input value that corresponds to g(x) = 13 is x = -10.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
