The standard form of linear equations is Ax + By = C where A and B ≠ 0, and A is non-negative.
Therefore, the correct answer is A) 6x - 7y = 8

20% by mass means 20 g of the NaOH is dissolved in 100 g of solution. If that is what you mean.
Step-by-step explanation: What is the meaning of 20% mass by volume solution?
20% mass by volume means 20 g of the NaOH is dissolved in 100 mL of the solution.
Depends on the concentration terms meaning and values also changes.
Your answer would be <span>x = 2/3

Answer:
-8
Step-by-step explanation:
well since the equation has the <em>same base</em> of 11, you can just solve for x as you normally would. so the question becomes:
4x+1 = 3x -7
<em>subtract one from both sides</em>
4x = 3x - 8
<em>subtract 3x from both sides</em>
x = - 8
