Tell whether the ordered pair is a solution of the linear system. (-4,-6); -3x+y=6, -2x+y=-8
harkovskaia [24]
Plug them in... -4=x -5=y

-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)

-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)

Therefore the ordered pair IS NOT the solution.

Hope this helps :)

Solve the equation.

Step-by-step explanation:

6c + 11= 2c + 59

Collect like terms

6c - 2c = 59 - 11

4c = 48

c = 48/4

c = 12

Hello need help please with Divide rational and simplify
aliina [53]
Dividing fractions is the same as multiplying by its reciprocal so you can change the equation to this
\frac{ - 14 + 7x}{4}  \times  \frac{4}{4 - 2x}
And you can simplify by eliminating the fours and multiplying straight across
\frac{ - 14 + 7x}{4 - 2x}
You can pull out - 7 from the top and 2 from the bottom so you have this
\frac{ - 7(2  -  x)}{2(2 - x)}
And then you can cancel out to (2-x) to get an answer of
\frac{ - 7}{2}
