Constant in a mathematical expression is a term whose value never changes.
The terms with x and y will vary based on the variable x and or y.
Answer: x=3
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- Multiply both sides of the equation by 3:

- Now you must make the equation equal to zero as following:

- Factor it, as you can see below. Therefore, you obtain the following result:

He would need a 93% on his fourth exam.
94+89+96+93= 372, 372 divided by 4= 93
Answer:
Substitute, <em><u>y = -3</u></em> and <em><u>x = k</u></em> on the equation.
=> k - 2×(-3) = -2
=> k = -2 + (-6)
=> k = - 8
