Question

В) z+12/45=14/45+19/45

Answer 1

Z=14/45+19/45-12/45
z=21/45=7/15

Answer 2

To solve the equation, we need to isolate the variable "z" on one side of the equation. Let's start by simplifying the right-hand side of the equation first:

z + 12/45 = 14/45 + 19/45

Now, let's add the fractions on the right-hand side:

z + 12/45 = (14 + 19)/45 z + 12/45 = 33/45

Next, let's subtract 12/45 from both sides to isolate "z" on the left-hand side:

z = 33/45 - 12/45 z = (33 - 12)/45 z = 21/45

Finally, we can simplify the fraction:

z = 7/15

So, the solution to the equation is z = 7/15.
