Step-by-step explanation:
By substitution method
6x+3(2x)=12
6x+6x =12
12x=12
x=1
y=2x
y=2*1
y=2
Answer:
Step-by-step explanation:
-3x +12 =x-4
+3x
12 = 4x -4
+4
16 = 4x
Divide by 4
4 = x
Answer:
Over
Step-by-step explanation:
<h3>hello!</h3>
=====================================================
Parallel lines have the same slope.
So if the given line has a slope of 3, then the line parallel to it has the same slope (3)
Now, let's write the equation of the line in Point-Slope Form.
Remember, point-slope form looks like so:-

Where
y₁ is the y-coordinate of the point that the line passes through
m is the slope
x₁ is the x-coordinate of the point that the line passes through
In this case,
y₁ is equal to -8
m is equal to 3
x₁ is equal to 1
Plug in the values:

Simplify:

and we're done!
