Question

1. Select ALL the equations that are equivalent to the equation 3x - 4 = 5.*
3x = 9
3x - 4 + 4 = 5 + 4
X - 4 = 2
X = 9
-4 = 5 - 3x

Answer 1

Answer:

3 x= 9

3x-4+4=5+4

Step-by-step explanation:

........

Answer 2

Here is the work to figure this out:

3x-4=5 —-> 3x=9 ——> x=3

3x=9 —-> x=3 EQUAL

3x-4+4=5+4 —-> 3x=9 —-> x=3 EQUAL

x-4=2 —-> x=6 NOT EQUAL

x=9 NOT EQUAL

-4=5-3x ——> -9=-3x ——> x=3 EQUAL

so it’s 3x=9, 3x-4+4=5+4, and -4=5-3x
