I'm not even going to bother with the substitution method.
Instead of all that, I just want to show you something:
Take the FIRST equation:
y - 2x = 8
Add 2x to
each side: y = 8 + 2x
Multiply each
side by 2 : 2y = 16 + 4x
Look at that ! The first equation says the same thing as the second one !
Both of them are actually the same equation.
You actually have only one equation, with 'x' and 'y' in it.
If you graph it, the graph is a straight line, and EVERY point
on the line is a solution of the equation.
==> There are an infinite number of solutions, because
they only gave you one equation, with two unknown variables.
To find a unique solution, you'd need two equations.
C.
First you must divide, 650/10. Which will equal to 65. Subtract 65 from 650. You will end up with 585. To represent the amount that is left would be 9/10,
<h2>
Answer:</h2>
The first step would be to multiply the bottom equation by -1 to eliminate x, then you would combine like terms, like 5y + 2y, and 16 + 10.
Answer:
b>5
Step-by-step explanation:
*Subtracted 4 from both sides and then divided both sides by 2*
If you are trying to factor it is 14(3a+b).
But if you are looking for the greatest common factor it is 14.
