Question

what is 3/4x+1=-8

Answer 1

You mean:
\[\frac{3}{4x} + 1 = -8\]
OR
\[\frac{3x}{4} + 1 =-8\]

Which one?

Answer 2

3/4x

Answer 3

\[\frac{3}{4}x + 1 = -8\]First subtract 1 on both sides, can you?

Answer 4

yes

Answer 5

-9

Answer 6

what about the left side f the equation ? :D

Answer 7

i dont know

Answer 8

\[\frac{3}{4}x+1=-8\] we are trying to isolate x \[\frac{3}{4}x+1-1 =-8 -1\]\[\frac{3}{4}x =-9\]

since 1-1=0

understood so far?

Answer 9

yes
now i mulitpy 4?

Answer 10

Right :D

Answer 11

what do you get?

Answer 12

-36

Answer 13

where's the otherside of the equation? :O

Answer 14

12?

Answer 15

12 what? 12 watermelons?

Answer 16

There is supposed a Mr. 'x' along with coefficient '12', don't you forget to bring him along, or he will get very mad, and get you a wrong answer. -.-

Answer 17

well this is how you get it

\[\frac{3}{4}x = -9\]multiply "both" sides by 4\[\frac{3}{4}x \times 4= -9 \times 4\]\[\frac{3}{\cancel{4}}x \times \cancel{4}= -9 \times 4\]\[3x = -9 \times 4 \]\[3x = - 36\]

Now can you divide "both" sides of the equatio by three and show me?

Answer 18

x=-12

Answer 19

Right!! Very Good~
