What number can you multiply ONE equation by in the following system to obtain a matching

Answer:

Multiply the second equation by 2

Step-by-step explanation:

Given

4x + 3y = 8

2x + 5y =12

Required

Get matching coefficient for elimination

4x + 3y = 8

2x + 5y =12

The coefficient of x in both expressions are factors.

So, we can multiply the second equation by 2 to get the coefficient of x in the first.

i.e.

2 * (2x + 5y = 12)

4x + 10y = 24

So, the system becomes:

4x + 3y = 8

4x + 10y = 24

<em>Now, x can be eliminated</em>

20 points<br> What is the value of p in the linear equation ?<br><br> −4<br> −2<br> 2<br> 4
Nikolay [14]

Answer:

p=-2

Step-by-step explanation:

24p+12-18p=10+2p-6  

Subtract what is to the right of the equal sign from both sides of the equation.

24p+12-18p-(10+2p-6)=0

Then pull out the like terms(factors)

Which is: 4p+8

=4(p+2)

Put that to 0 and 4=0 which is not a solution because it's a non-zero constant.

So now put  p+2=0, subtract by 2 on both sides and the 2 cancels out and on the right side you have -2

p=-2
