Question

Use the equation y = 2x -5 to find y when x = 3z.

Enter your answer without spaces.

Answer 1

y = 6z - 5

Explanation:

Start with the given function y = 2x -5. Substitute the given 3z for x:

y = 2(3z) -5

Simplify this through multiplication:

y = 6z - 5

Answer 2

y=2(3z)-5
y=6z-5

Substitute x with 3z.
