Answer:
x = -1/24
Step-by-step explanation:
8 - 1/3x = 16
8 × 3x - 1/3x = 16
24x - 1/3x = 16
24x - 1 = 16 × 3x
24x - 1 = 48x
1 - 24x = - 48x
1 = 24x - 48x
1 = - 24x
-1/24 = x
x = -1/24
7x-y=14 :add 'y' to both sides
7x=14+y :divide both sides by 7
x=(14+y)/7 or x=2+(y/7)
Answer:
I'm kinda guessing 35 degrees.
Step-by-step explanation:
It was simple math and I don't know if there's a certain way you are supposed to do this. Sorry if I'm incorrect.
The correct expression that is equivalent to the algebraic expression -5x - 15 + 25x - 30 is -5(-4x + 9).
<h3>How to determine the equivalent expression</h3>
We shall simplify the given algebraic expression by carrying out basic mathematics operations as follows;
Given: -5x - 15 + 25x - 30
we group like terms together
25x - 5x - 15 - 30
20x - 45
the number 5 is a common factor of 20x and 45, so we have that;
5 × 4x - 5 × 9
by factoring out 5
5(4x - 9)
also;
5(4x - 9) = -5(-4x + 9)
Therefore, -5(-4x + 9) is an equivalent expression to the algebraic expression -5x - 15 + 25x - 30

Answer: If you were to graph the solution it would be evident. One solution is when the lines meet at one point, no solution is when the lines are parallel to each other (they do not touch) and infinitely solutions happens when the two lines are on top of each other.
