Answer:
x = 3
Step-by-step explanation:
3=5x-12
Rearrange the Equation.
5x - 12 = 3
Add 12 to both sides.
5x - 12 + 12 = 3 + 12
Simplify
5x = 15
Divide both sides by 5
5x/5 = 15/5
x = 3
Answer:
f(5) = 22
Step-by-step explanation:
When we want to solve for f(x) = 5x - 3 when x is 5, all we have to do is plug in 5 as x into the equation.
f(x) = 5x - 3
f(5) = 5(5) - 3
5 * 5 = 25
25 - 3 = 22
f(5) = 22
I hope this helps you!
