4x – 2y = 33
x + 2y = 17
How to solve by using elimination

X=10, Y= 3 1/2

Step-by-step explanation:

4x-2y=33 i

X+2y=17 ii

Adding equation I and ii

5x=50 divide both side by 5x

X=10

Substitute 10 for x in equation I we have,

10+2y=17

2y=17-10, collect the like term

2y=7 divide bother sides by 2

y=7/2,further division give us

Y= 3 1/2.

the answer is c)8

step-by-step explanaction:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
