Answer:

Therefore the results from adding the equation in this system is

$7x=-35$

Step-by-step explanation:

Given:

Equations as

$11x-3y=-17$ .......................1

$-4x+3y=-18$ .......................2

To Find :

Result when adding equation 1 and 2 = ?

Solution

On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18) as shown below

11x - 3y = -17

-4x + 3y = - 18

-------------------------------------------

7x + 0 = - 35

---------------------------------------------

Therefore the results from adding the equation in this system is

$7x=-35$

onji has $5.25 in nickels and dimes.The coin value can be modeled by the equation 0.10d + 0.05n = 5.25, where d represents the n

Maru [420]

This is how you solve this problem:
.10d + .05n = 5.25

(plug in the number of dimes we have)

(21 x .1) + .05n = 5.25

(multiply number of dimes x value of the dime)

2.10 + .05n = 5.25

(subtract 2.10 from both sides)

.05n = 3.15

(divide both sides by .05 to get the number of nickels)

n = 63 nickels

Hope this helps!
