Question

the perimeter of triangle is 34 cm. the second side is 8 cm less than the first side is 4 cm more than the 2nd side. the furst side is unknown. Write algebraic equation. Also please explain it.​

Answer 1

Let the fist side be x

Then second side will be x-5

Third side will be x-5+3 =x-2

Perimeter =14cm

x+x-5+x-2=14

3x-7=14

3x=21

x=7

So fist side is 7cm

Second side is 2cm

And third side is 5cm
