could you write a formal proof of this?
2. given: 2x -4 = 6x - 8 prove: x = 1

step-by-step explanation:

2x - 4 = 6x - 8

8 - 4 = 6x - 2x

4 = 4x

1 = x

hey casatellicater!

hope you're doing great today : )

they want us to prove that x actually equals 1. so let's prove.

if you've ever had to 'check your work' on a worksheet, this is exactly the same! so all we need to do is plug in x for 1!

our equation should look like: 2(1)-4=6(1)-8

i'm sure you know how to solve from there, can you do it? if you struggle just let me know below! : )

check your work with me when you finished solving.

2nd one in the first row is correct

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
