+76 In an isosceles triangle, the length of one of the two equal sides is 3 less than twice the third side. If the perimeter of the triangle is 19 cms, what is the length of each side?

Let the different side be x units long
The equal sides are both 2x-3 units long
The perimeter is 19
so
19= x+ 2x+3 + 2x+3
Can you finish it?
