Substitute the 1st equation in the 2nd, we get:

3x + 2(-3 + 2x) = 2
3x -6 +4x = 2

7x = 8
x = 8/7

Replace x = 8/7 in equation 1,

y = -3 + 2(8/7) = -3 +16/7 = -5/7

Y=-3+2x
3x+2y=2

3x+2(-3+2x)=2
3x-6+4x=2
+6 +6
7x=8
/7 /7
x= 8/7

Now plug that in to find y

y=-3+2(8/7)
-3+16/7
-3+2 2/7
y=-5/7

Solve the equation x^2=26
Volgvan

Take the square root. The opposite of squaring something is taking the root :)

√x^2 = √26

x = √26

x = 5.099...

OR leave it if your teacher doesn't want a decimal since it can't be simplified anymore

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W
Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2         46.5

5         116. 25

7         162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

2 \; \rm Jackets =\$ 46.50

1 \;\rm Jacket = \dfrac {\$46.50}{2}

1 \;\rm Jacket = \$ 23.25

Now the cost price of 3 jackets is given as,

3\;\rm Jackets = \$23.25 \times 3

3\;\rm Jackets = \$69.75

Hence we can conclude that the cost price of 3 jackets is $69.75.

To know more about the cost price, follow the link given below.
