Solve the following system of equations<br>2x – 3y = 6<br>4x+2y=4​
FinnZ [79.3K]

Answer:

\boxed{(\frac{3}{2} ,-1)}

Step-by-step explanation:

\left \{ {{2x-3y=6} \atop {4x+2y=4}} \right.

It seems this system of equations would be solved easier using the elimination method (the x and y values are lined up).

Multiply everything in the first equation by -2 (we want the 4x to be able to cancel out with a -4x).

2x-3y=6 \rightarrow -4x+6y=-12

Now line up the equations (they are already lined up - convenient) and add them from top to bottom.

\left \{ {{-4x+6y=-12} \atop {4x+2y=4}} \right.

The -4x and 4x are opposites, so they cancel out.

Adding 6y and 2y gives you 8y, and adding -12 and 4 gives you -8.

8y=-8

Divide both sides by 8.

y=-1

Since you have the y-value you can substitute this in to the second (or first equation, it doesn't necessarily matter) equation.

4x +2(-1)=4

Simplify.

4x -2=4

Add 2 to both sides.

4x=6

Divide both sides by 4.

x=\frac{6}{4} \rightarrow\frac{3}{2}

The final answer is x=\frac{3}{2} ,~y=-1.

(\frac{3}{2} ,-1)

Determine whether y varies directly with x. y-2x=0
skelet666 [1.2K]
<span>hi,  </span>
<span>you can determine it by seeing if y/x = a constant value, in other words if y = (a constant value) x </span>
<span>then you say that y varies directly with x, and you can see that : call the constant k </span>
<span>then y/x is supposed to be k in all values </span>
<span>6/3 = 2 </span>
<span>24/12 =2  </span>
<span>96/48 = 2 </span>
<span>384/192 = 2 </span>
<span>it worked the ratio between x and y is constant so y varies directly with x ( y = 2x) and that constant k =2 </span>
<span>p.s. you can also say that x varies directly with y but in that case it becomes x/y =constant and that constant say c is 1/2 (x = (1/2)y)) </span>
<span>hope u understand.

Help me as quick as possible <br> 11x+4y=12<br> 9x-4y=8<br> Solve it with elimination method
Firdavs [7]

Answer:

x = 1, y = 1/4

Step-by-step explanation:

11x + 4 y = 12   \ \ \ ---( 1)\\9x -4y = 8 \ \ \  - - - (2)\\\\(1) + ( 2 ) => 20x + 0 = 20\\\\

            => x = 1

Substitute x = 1 in ( 1 ) :  

                            11 + 4y = 12\\4y = 12 - 11\\\\y =\frac{1}{4}
