Since AB and AC are equal then 5x - 4 = 3x and solve that
5x - 4 = 3x
2x - 4 = 0
2x = 4
x = 2
plug 2 in for x
5(2) - 4 = 10 - 4 = 6 (the length of AB)

First you'll find the value of x. This is an equilateral triangle to we can set side AB equal to AC.
5x - 4 = 3x
5x = 3x + 4
2x = 4
x = 2
For the length of side AB we will plug in the value of x in the expression.
5(2) - 4
10 - 4
6 = AB
