Which equation could represent a linear combination of the system?
Ghella [55]

The equation that could represent a linear combination of the system 2/3x + 5/2y = 15 and 4x + 15y = 12 is 0 = 26

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change, slope or gradient

<h3>How to determine the linear combination to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

2/3x + 5/2y = 15

4x + 15y = 12

Multiply the first equation by 6, to eliminate the fractions.

6 * (2/3x + 5/2y = 15)

This gives

4x + 15y = 90

Subtract the equation 4x + 15y = 90 from 4x + 15y = 12

4x - 4x + 15y - 15y = 12 - 90

Evaluate the difference

0 + 0 = -78

Evaluate the sum

0 = -78

The above equation is the same equation as option (b) 0 = 26

This is so because they both represent that the system of equations have no solution

Hence, the equation that could represent a linear combination of the system is 0 = 26

X=-6
You plus in x as -6 and you already know that y=5x and you plug in x=-6
It should look like 2(-6)-5(-6)=18

A+c=r-d covert the equation to solve for a plz answer asap!!!!
FinnZ [79.3K]

Answer:

a= r- d - c

Step-by-step explanation:

Converting the equation to solve for a really just means getting a alone on one side of the equation.

a + c = r - d

To get a alone on the left, we can subtract c from both sides:

a+ c = r -d\\a = r - d - c (Since c - c = 0, c will disappear from the left side.)

Answer: a= r- d - c
