Answer:

AB = 13

BC = 9

Step-by-step explanation:

AC = AB + BC

AC = (4x - 3) + (2x + 1)

AC = 6x - 2

If AC = 22.....,

then we equate the statements..so that we can obtain the value of x

; 6x - 2 = 22

; 6x = 24.....hence giving...x = 4

Then back to the question...if x = 4

then..,

;AB = 4(4) - 3

;AB = 13

;BC = 2(4) + 1

;BC = 9
