Answer:

b = 1

Step-by-step explanation:

-18+4b=7(4)+(7)-(6b)

-18+4b= 28 + (-42b)

4b-16=-42b+28

Add 42b to both sides.

4b-16+42b=-42b+28+42b

46b-18=28

Add 18 to both sides.

46b-18+18=28+18

46b=46

b= 46/46

b=1

Given the formula:<br><img src="https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%20%2B%20a%7D%7B1%20-%20a%7D%20" id="TexFormula1

$12 = \frac{1+a}{1-a} => 12(1-a)= 1+ a \\=> 12 -12a = 1 + a => 12a+1 = 12-1 \\=> 13a = 11 => a= \frac{11}{13}$

ok done. Thank to me :>
