Ab over 2 equal 2a minus 1,express a in terms of b

= 2a - 1

2() = 2(2a - 1) multiplied both sides by 2

ab = 4a - 2 distributed the 2 on the right side

ab - 4a = -2 subtracted 4a from both sides

a(b - 4) = -2 factored out "a" from the left side

a = divided (b - 4) on both sides

a =

if you mean

then it's c. 8, -7/3

but if you mean

then it is

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25
