Question

Question 1.1. Consider the system of equations: 3x + 2y = 18 and x – 2y = 14.

What property is used to transform the equation x – 2y = 14 into – 3x + 6y = – 42?
(Points : 1)
addition property of equality
substitution property of equality
multiplication property of equality
division property of equality

Answer 1

x*3 = 3x
2y*3 = 6y
14 *3 = 42
can you sort of see what the answer should be?

Answer 2

sorry
but no

Answer 3

what do you do each time? you multiply by three
what property is it then?

Answer 4

Multiplication property of equality?

Answer 5

yes

Answer 6

hehe
"Multiplication property of equality" <---- what does that mean?

Answer 7

ok Thank u so much

Answer 8

when you multiply both sides of the equation by the same number @jdoe0001

Answer 9

well
@Mehek14 yes, but he/she's just picking a choice, rather than understand what's being done

Answer 10

picking prefabricated options and actually understanding, is not exactly the same thing
