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.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
