Is the open sentence 3z=2z+5 true or false when z=5?<br><br> A. True<br> B. False

inna [77]

Hey there!

If z = 5

we replace "z" with "5"

So, let's test out the problem to see if it is true or false

Problem becomes: $3(5) = 2(5) + 5$

Let's work this out

$3(5) = 15$

Problem becomes: $15 = 2(5) + 5$

$2(5) = 10$

Problem becomes: $15 = 10 + 5$

$10 + 5 = 15$

So, therefore it looks like this statement/ sentence is $True$ !
