a.

x + 9 = 7

x = 7 - 9

x = - 2

b.

23 - y = 44

- y = 44 - 23

- y = 21

y = - 21

c.

s + 19 = 26

s = 26 - 19

s = 7

d.

m - 40 = 20

m = 20 + 40

m = 60

e.

z + 100 = 100

z = 100 - 100

z = 0

f.

x + 22 = 23

x = 23 - 22

x = 1

g.

s - 4 = 96

s = 96 + 4

s = 100

h.

1/4x = 4

x = 4 / 1/4

x = 4 * 4/1

x = 16

i.

24x = 3

x = 3/24

x = 1/8

j.

1/10x = 50

x = 50 * 10/1

x = 500

k.

1/11y = 33

y = 33 * 11/1

y = 363

l.

t + 14 = 16

t = 16 - 14

t = 2

m.

t - 1 = 16

t = 16 + 1

t = 17

n.

1/2q = 8

q = 8 * 2/1

q = 16

o.

15t = 24

t = 24/15

t = 8/5

Sylvie bought 13 bagels and a container of cream cheese.Each bagel cost the same price.The cream cheese cost $2.95.Sylvie spent
Taya2010 [7]
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50 <u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

7.50=2.95+13(b)

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as 

4.55=13 (b)

Now, to get "b" by itself, you must divide 13 on both sides, resulting as

.35=b

This will answer your question as the cost of 1 bagel would be $0.35 per bagel.
