Question

Ian has 24 more pencils than Sylvia. Ian has 4 times as many pencils as she has. How many pencils should Ian give to Sylvia so they will have an equal number of pencils?

pake cara nya ya!!!

Answer 1

Let Ian = I and Sylvia = S

| = 24 + S
| = 4S

I = I
so,
4S = 24 + S
4S - S = 24
3S = 24
S = 24/3
S = 8

I = 24 + S
I = 24 + 8
I = 32

32 - x = 8 + x
-x -x = 8 - 32
-2x = -24
2x = 24
x = 24/2
x = 12

Answer 2

Pensil ian = i
pensil sylvia = s

s = i- 24
s = 4i

i-24 = 4i

4(i-24) = i

4i-96=i

4i-i= 96

3i=96

i=32

s=32-24
= 8

---

i + s

32 + 8 = 40

40:2=20

20-8= 12

jadi ian harus memberi 12 pensil kpd sylvia agar mereka berdua punya 20 pensil
