Question

Solve -4b + 2 = 18.

b =

Answer 1

simple algebra

Answer 2

i am not good algebra

Answer 3

ok first subtract 2 from both sides, it will leave you with -4b=16. then divide both sides by -4 and you get b= -16/4 or -4

16

Answer 6

so b= -4

Answer 7

ok -4 times -4? = 16 so b=-4

Answer 8

yup

Answer 9

So the first step is to change the plus to a minus
-4b - 2 = 18
subtract 2 from both sides of the equation,
\(−4b+2−2=18−2\)
Which equals −4b=16
So then divide both sides -4
\(\LARGE\frac{-4b}{-4}=\frac{16}{-4}\)
\(\cancel{\color{red}{\LARGE\frac{-4b}{-4}}}=\frac{16}{-4}\)
So \(\frac{-4b}{-4}\) cancels
all you have left is \(\frac{16}{-4}\)
simplify that then you have your answer.
