What is the solution to the system of equations?
1 answer:
Answer:
A: There is no solution
Step-by-step explanation:
This is not a very likable question.
Y=3x-4
9x-3y=14
Put the y value from the first equation into the second.
9x - 3(3x - 4) = 14 Remove the brackets
9x - 9x + 12 = 14 Combine like terms on the left
12 = 14 When you get this kind of conclusion, that means there is no solution. I'll graph these two for you.
Blue: y =3x - 4
Green: 9x - 3y = 14
They never touch they never meet: they are parallel. They don't give a solution.

Answer: x = 5/2 = 2.5
Step-by-step explanation:
<u>Given expression</u>
2x (x + 3) = 2x² + 15
<u>Expand parentheses and apply the distributive property</u>
2x · x + 2x · 3 = 2x² + 15
2x² + 6x = 2x² + 15
<u>Subtract 2x² on both sides</u>
2x² + 6x - 2x² = 2x² + 15 - 2x²
6x = 15
<u>Divide 6 on both sides</u>
6x / 6 = 15 / 6
x = 15/6

22% in fraction form is or 0.22, but it isn't the simplest form.
To put into a simplest form, you must divide the numerator <em>and </em>the denominator by a common multiple.
or 0.22 is divisible by 2. Therefore, you can divide
by 2.
