Answer:
x=6
Step-by-step explanation:
To find the perimeter of the triangle you need to add up all the sides, so if all the sides are 2x-3 the equation will look like this;
2x-3+2x-3+2x-3=27
which when combining like terms will leave it to be;
6x-9=27
Than move all the factors besides x over to the right side;
6x-9+9=27+9
6x = 36
6x/6 = 36/6
x = 6
so your answer will be x=6
