5c-6=4-3c<br>2c-6=4<br>2c=10<br>c=5<br>describe the error made in the problem.​
SVETLANKA909090 [29]

Answer:

5(c) - 6 = 4 - 3(c) is wrong

Step-by-step explanation:

The other problems are correct and equal. This one is wrong because when you do the equations you get 19 = -11 which is clearly not equal. You would need to change the equation to make it equal. So it would be:

5(c) - 6 = 4 - -3(c) so now it is 19 = 19.

So you would change 5(c) - 6 = 4 - 3(c)  into 5(c) - 6 = 4 - -3(c)

<em>I hope this helps :)</em>

Answer:

The end result would be 0>-11

Step-by-step explanation:

Subtract 7 from each number and then just write it again.

7 - 7 = 0

-4 - 7 = -11

0>-11

Which of these describes the system of linear equations below?
Nataly [62]

Given:

The system of equations is

3x-2y=7

6x-4y=14

To find:

The correct statement for the given system of equations.

Solution:

On comparing the given equations and general form of linear equation, i.e., ax+by+c=0, we get

a_1=3,b_1=-2,c_1=-7

a_2=6,b_2=-4,c_2=-14

Here,

\dfrac{a_1}{a_2}=\dfrac{3}{6}=\dfrac{1}{2}

\dfrac{b_1}{b_2}=\dfrac{-2}{-4}=\dfrac{1}{2}

\dfrac{c_1}{c_2}=\dfrac{-7}{-14}=\dfrac{1}{2}

Since, \dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}, therefore, the two equations are equivalent and the system has infinitely many solutions.

Hence, the correct option is b.

2x + 4y =8<br> X = 3y -6
Sergio [31]

{x,y} = {-2,3}

 [1]    2x + 4y = 8

  [2]    x - 3y = -11

 4y + 2x = 8      

-3y + x = -11  

Solve equation for the variable  x  

 [2]    x = 3y - 11

Plug this in for variable  x  in equation [1]

  [1]    2•(3y-11) + 4y = 8

  [1]    10y = 30

Solve equation [1] for the variable  y  

  [1]    10y = 30  

  [1]    y = 3  

By now we know this much :

   x = 3y-11

   y = 3

Use the  y  value to solve for  x  

   x = 3(3)-11 = -2  

Solution :

{x,y} = {-2,3}
