Answer:

X=5

AB=13

BC=17

Step-by-step explanation:

So first you add the two equations together and the total will have to be 30.

So, 2x+3-4x-3=30

Simplified 6x=30

x=5.

2x+3 -> 5 times 2 + 3

4x - 3 -> 5 times 4 - 3

Answer:

Step-by-step explanation:

AB + BC = AC

2x +3 + 4x - 3 = 30

2x + 4x + 3 - 3 = 30

Combine like terms

6x = 30

Divide both sides by 6

x = 30/6

x = 5

AB = 2x + 3 = 2*5 + 3 = 10 + 3

AB = 13

BC = 4x - 3 = 4*5 - 3 = 20 - 3

BC = 17
