The perimeter of a triangle with two equal sides is 46 cm. if it's base were lengthened by 3 cm and each leg were shortened by 5 cm, all three sides would be equal. find the length of the base of the original triangle

The original triangle has sides of 18 cm, 18 cm and 10 cm

Step-by-step explanation:

Let x cm be the length of the leg of the original triangle and y cm be the length of the base of the original triangle.

1. Since the perimeter of the original triangle is 46 cm, then

x+x+y=46.

2. If it's base were lengthened by 3 cm, then it becomes y+3 cm. If each leg were shortened by 5 cm, then each leg becomes x-5 cm. All three sides became equal, then

y+3=x-5.

3. Solve the system of two equations:

Then

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
