Answer :
The value of x from the given linear function is 15
Solving linear function
A linear function is a function hat has a leading degree of 1
Given the equation below;
2/5x +9 =15
Subtract 9 from both sides
2/5x + 9 - 9 = 15 - 9
2/5x = 15 - 9
2/5x = 6
Multiply both sides by 5
2/5x (5) = 6(5)
2x = 30
x = 15
Hence the value of x from the given linear function is 15
