Answer:
-6
Step-by-step explanation:
in the equation y = mx + b, the b part is the y-intercept
For this case we have the following equation:

From here, we must clear the value of x.
For this, we follow the following steps:
1) Place the variable on one side of the equation and the constant on the other side of the equation:

2) Make common factor x:

3) Clear the value of x:

Answer:

The relationship between x and the difference of a - b is inversely proportional.
Answer:
Step-by-step explanation:
2x+y=8x-y=4
First solve take all x variable to one side and all the y on one
y+y=8x-2x=4
2y=6x=4
Solve for x solve for y
6x=4 2y=4
x=4÷6 y=2
x=4/6
Easy, just make 2 thingummies cancle each other
like this
(2x+3) and (-2x+4)
the sum is 7 because x's cancel
or
(2x-3) and (4x+3),
the sum is 6x because -3 an 3 cancel
