Answer:
10/3
Step-by-step explanation:
|x+3|=4x-7
So |-(x+3)|=|x+3|
We are going to try out two cases:
-(x+3)=4x-7 and x+3=4x-7
-x-3=4x-7 3=3x-7
-3=5x-7 10=3x
4=5x x=10/3
x=4/5
We are going to test out both because we could something that isn't actually a solution, this is called extraneous.
First thing I'm going to check is 4x-7 for it being positive.
4(4/5)-7=20/5-7=-15/5=-3 so 4/5 will not work because absolute value result can't be negative
4(10/3)-7=40/3-7=19/3 which is positive
checking |x+3| to see if is 19/3 for x=10/3 we see that is so that is the answer
Is that a trick question wouldn't it be 20??? I'm confused
Start with the point-slope form: 
.
Then you substitue in the slope and coordinates from the point:
You don't do a lot of clean up to the form, with the exception of turning "minus negative 7" into "plus 7".
Thar be yer answer!
Answer:
x-y=4
Step-by-step explanation:
y=x−4
The standard form of a linear equation is
Ax+By=C.
Rewrite the equation with the sides flipped.
x−4=y
Move all terms containing variables to the left side of the equation.
Tap for more steps...
x−y−4=0 Add 4
to both sides of the equation.
x−y=4

Answer:
7*5 + -29
Step-by-step explanation:
She makes 7 payments of 5 to the store
7*5
Then she gets 29 dollars back so that would be negative
+ -29
7*5 + -29
35 -29
She has paid 6 dollars to the store
