Answer:

10

Explanation:

Solve f(x)=2, if f(x)=1/2x-3

Both equations are set to equal f(x) so the solution would be the two equations set to equal each other

2 = 1/2x - 3

==> add 3 to both sides

5 = 1/2x

==> multiply both sides by 2

10 = x

Answer:

x = 10

given:

f(x) = 2

======


\sf \rightarrow (1)/(2) x- 3= 2

change side


\sf \rightarrow (1)/(2) x= 2+3

simplify the following


\sf \rightarrow (1)/(2) x= 5

change side


\sf \rightarrow x= 5*2

final outcome


\sf \rightarrow x= 10
