Answer 4

what you need to find is just x, right?

Answer 5

i dont know </3

Answer 6

The question is asking how many free throws Felix made and x represents the free throws, so we just need to solve x

x+2y+3z=520
x+20=y
y=3.5z

Answer 7

is it 520 div 3.5?

Answer 8

x+2y+3z=520---(1)
x+20=y---(2)
y=3.5z---(3)

substitute (3) into (2),
x+20=3.5z---(4)

Sub (3) into (1),
x+2(3.5z)+3Z=520---(5)

just solve (4) and (5), and you can find x and z. but x is the answer

Answer 9

nope, not just divide it

Answer 10

im lost

Answer 11

i haven't read the long question, but i just use the equation it given

Answer 12

equations*

Answer 13

simplify those three equations into simultaneous equations

Answer 14

how tho is the question im slow

Answer 15

there are three questions on the screen, right?

Answer 16

ya

Answer 17

do i put the 530 and 20 and - tjhem?

Answer 18

no need. let's do it step by step

Answer 19

ok

Answer 20

firstly, don't re-read the question. just look at these three equations

Answer 21

ok

Answer 22

and look at my previous drawing. ask if you don't understand this step

Answer 23

how u get 1 and 2

Answer 24

1 represents equation one.
and so on.

Answer 25

x+2y+3z=520---(1)
this is equation one.

x+20=y---(2)
this is equation two.

y=3.5z---(3)
this is equation three.

Answer 26

ok

Answer 27

actually, have you ever learnt simultaneous equations?

Answer 28

noo

Answer 29

ohhhhh, no wonder why you don't know what i am saying...

Answer 30

simultaneous equations is about two equations with two unknowns, and we can find these two unknowns with some easy steps. let me start again

Answer 31

x+2y+3z=520---(1)

x+20=y---(2)

y=3.5z---(3)

although there are three unknowns, we can simplify them into two unknowns.
it's given that y=3.5z.

Answer 32

still lost...

Answer 33

don't feel messy, it can be very simple.
there are three unknowns, right?
and equation three is given that y=3.5z
is it ok here?

Answer 34

yes

Answer 35

ok. can you see there're "y"s in equation one and two?

Answer 36

yes
