Example 1:
y=4
5
y=4
5 1
y=4
5 1
Original equation
Put the whole number
(4) over one.
Cross multiply
5(4) = 1(y)
20 = 1y
y = 20
Solution
Check:
y=4
5
20 = 4
5
4=4
Original equation
Substitute your
answer to check
to see if the two
sides are equal.
Example 2:
12 = z
4
12 = z
1 4
12 = z
1 4
Original equation
Put the whole number
(12) over one.
Cross multiply
1(z) = 12(4)
1z = 48
z = 48
Solution
Check:
12 = z
4
12 = 48
