Question

b/-3+5=7

Answer 1

\( \color{Black}{\Rightarrow {-b \over 3} = 7 - 5 }\)

\( \color{Black}{\Rightarrow {-b \over 3} = ?}\)

Answer 2

yes that's the question

Answer 3

So, you multiply both sides by 3.
Can you manage to do that?

Answer 4

when u say multipy both sides by 3 you mean multiply 7*3 and 5*3

Answer 5

What? nope..\[ \color{Black}{\Rightarrow {b \over -3} = 7- 5 }\]What's 7 - 5?

Answer 6

2

Answer 7

That's right. We have \[ \color{Black}{\Rightarrow {b \over -3}=2 }\] Now we have to multiply both sides by 3.

Answer 8

\[ \color{Black}{\Rightarrow {b \over -3} \times 3 = 2 \times 3 }\] Do you get it?

Answer 9

yes i got that

Answer 10

What does it simplify to?

Answer 11

-3*3=9
2*3=6

Answer 12

Oops.\[ \color{Black}{\Rightarrow {b \over \cancel{-3}^{-1} } \times \cancel{3} = 2 \times 3 }\] Remember that -3 is the denominator; not the numerator!

Answer 13

o ok so u just do 2*3=6

Answer 14

Yeah.

Answer 15

\[ {-b \over 3} \times 3 =6 \]\[ \color{Black}{\Rightarrow -b = 6 }\]

Answer 16

o ok thank you so much
