<em>Answer,</em>

<h2>-2</h2>

<em>Explanation,</em>

<em>-1/3 - 1 2/3 </em>

<em>Factor  out common term -1                                                                                              =</em> - (1/3 + 1 2/3)

<em>Add whole numbers </em>

0 + 1 = 1

<em>Combine Fractions</em>

1/3 + 2/3

<em>Since the denomonators are the same add the fractions</em>

1 + 2/ 3

<em>Add the numbers 1 + 2 = 3</em>

3/3

<em>Apply the rule a/a = 1</em>

3/3 = 1

<em>Finnaly </em>

<h3>-(1 + 1) = -2 </h3>

First one is wrong bcs it should be smaller than the answer.
The second one is correct bcs to find the second number we need to do inverse operation, here is subtraction.
Third one is correct bcs this is the same (but if u r searching only for relating not same, then the third kind of wrong)

Help please??<br> Solve using substitution:<br> 8x + 2y=13<br> 4x + y=11
Hoochie [10]
Solve for y in one of the equations.

4x + y = 11
Subtract 4x from both sides.
y = -4x + 11

Substitute y in the other equation.

8x + 2(-4x + 11) = 13
Simplify.
8x + -8x + 22 = 13
Subtract 22 from both sides.
0 = -9

No solutions.

Which system of equations is equivalent to the following system? 3x + 5y = 29 x + 4y = 16 3x + 5y = 29 −x − 4y = 16 3x + 5y = 29
sp2606 [1]

Answer:

Option 3x+5y=29 and -3x-12y=-48 is the system of equations equivalent to the given system of equations 3x+5y=29 and x+4y=16

Step-by-step explanation:

Given system of equations  is 3x+5y=29 and x+4y=16

To find the equivalent system of equations to the given system of equations :

Option 3x+5y=29 and -3x-12y=-48 is the system of equations represents the given system of equations.

Because we can write the given equations as below

3x+5y=29 and x+4y=16

x+4y=16 rewritting as below

When multiply the above equation into (-3) we get

(-3)\times (x+4y)=16\times (-3)

-3x-4y=-48 as same as the equation x+4y=16 so we can say that they are equivalent

Therefore Option 3x+5y=29 and -3x-12y=-48 is the system of equations represents the given system of equations

Therefore 3x+5y=29 and -3x-12y=-48 is the system of equations equivalent to the given system of equations 3x+5y=29 and x+4y=16
