What is the solution to the following system of equations? 4x + 2y = 18 x − y = 3
Ber [7]

For this case we have the following system of equations:

4x + 2y = 18\\x-y = 3

To solve, we clear "x" from the second equation:

x = 3 + y

We substitute "x" in the first equation:

4 (3 + y) + 2y = 18\\12 + 4y + 2y = 18\\12 + 6y = 18

We clear the value of the variable "y":

6y = 18-12\\6y = 6\\y = \frac {6} {6}\\y = 1

We look for the value of the variable "x":

x = 3 + y\\x = 3 + 1\\x = 4

Thus, the solution of the system is given by:

(x, y) :( 4,1)

Answer:

(x, y) :( 4,1)

(100 points) find the cost of each treat
Anna71 [15]

Answer:

icecream = $2.99

donut = $1.19

creamcake = $4.99

Step-by-step explanation:

The picture shows $7.17 for 2 x ice-cream and 1 donut

We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99

9.17- 4.99=4.18

=5.37-4.18 =1.19

we can then fill out the boxes.

1.19 +1.19 = 2.38 = 5.37-2.38= £2.99

2.99 +2.99 +1.19 = $7.17

We can see total first two rows = $12.56

2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56
