Question

Variable expression 4-5h

Answer 1

Set the expression equal to 0.
4 - 5h = 0

Add 4 on both sides.
5h = 4

Divide by 5 on both sides.
h =
`\fbox {4/5}`

Answer 2

Given:
4-5h

* an algebraic equation is always equal to 0.
4 - 5h = 0
Find the value of h.
4 - 5h = 0
-5h = -4
-5h/-5 = -4/-5
h = 4/5

To check: substitute h by its value.
4 - 5h = 0
4 - 5(4/5) = 0
4 - 20/5 = 0
4 - 4 = 0
0 = 0
