Answer:

x = 5

AB = 13

BC = 17

Explanation:

So we have to make an equation;

(2x + 3) + (4x - 3) = 30

Collect like terms

6x = 30

Divide both sides by 6

x = 5

To find AB we have to plug in the value of x;

2x + 3 = 2(5) + 3

10 + 3 = 13

AB = 13

To find BC we also have to plug in the value of x;

4x - 3 = 4(5) - 3

20 - 3 = 17

BC = 17
