Answer:

x = -7, y = -9

Step-by-step explanation:

The coefficient (the number before) the y is the same but the signs are opposite so add the equations together:

x-3x+y-y=-16+30

-2x=14

x=-7

y=-16-x=-16--7=-9

Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number

Tanzania [10]

Given:

The equation is

$\begin{gathered} 6x+4y=16 \\ \\ 9x+6y=24 \end{gathered}$

Find-:

The solution of the equation

Explanation-:

The first equation is

$\begin{gathered} 6x+4y=16 \\ \\ 2(3x+2y)=16 \\ \\ 3x+2y=\frac{16}{2} \\ \\ 3x+2y=8 \end{gathered}$

The second equation is

$\begin{gathered} 9x+6y=24 \\ \\ 3(3x+2y)=24 \\ \\ 3x+2y=\frac{24}{3} \\ \\ 3x+2y=8 \\ \end{gathered}$

Both equations are the same.

For slove, the two unknown variables need two equations.

So,

There is NO SOLUTION

An equation is shown below. 12 - 9 + c = 12 What value of c makes the equation true?

kvasek [131]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ 12 - 9 = 3

3 + c = 12

c = 12 - 3

c = 9
