Question

If AB = 3x + 5, BC = 2x + 8, and AC = 88, what is the value of x?

Answer 1

15

Explanation:

AB + BC = AB

3x + 5 + 2x + 8 = 88

5x + 13 = 88

5x = 88 - 13

= 75/5

= 15

Hope this helps!

Answer 2

x = 15

Explanation:

AB + BC = AB

3x+5 + 2x+8 = 88

Combine like terms

5x +13 = 88

Subtract 13 from each side

5x+13-13 = 88-13

5x = 75

Divide each side by 5

5x/5 = 75/5

x = 15
