2x + 6 = 4x + -2
Reorder the terms:
6 + 2x = 4x + -2
Reorder the terms:
6 + 2x = -2 + 4x
Solving
6 + 2x = -2 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
6 + 2x + -4x = -2 + 4x + -4x
Combine like terms: 2x + -4x = -2x
6 + -2x = -2 + 4x + -4x
Combine like terms: 4x + -4x = 0
6 + -2x = -2 + 0
6 + -2x = -2
Add '-6' to each side of the equation.
6 + -6 + -2x = -2 + -6
Combine like terms: 6 + -6 = 0
0 + -2x = -2 + -6
-2x = -2 + -6
Combine like terms: -2 + -6 = -8
-2x = -8
Divide each side by '-2'.
x = 4

When the slope is zero, the line is horizontal. Its equation will be of the form
... y = constant
The y-value of your point is specified as -9, so the equation of the line through that point is
... y = -9
Answer:
70 gallons
Step-by-step explanation:
x gallon of 50%
x * 0.5 + 70 * 0.3 = (x + 70) * 0.4
0.5x + 21 = 0.4x + 28
0.1x = 7
x = 70
