Question

the side of a square is (x+8) m and the other side is (3x-18) m. Find the value of x

Answer 1

In a square, all sides are equal.

Therefore:-

3x-18=x+8

3x-x=8+18

x=26/2

x=13

Answer 2

We know that, sides of square are equal. So, (x+8)=(3x-18)
x+8=3x-18
x-3x=-18-8
-2x=-26
2x=26
x=26/2
x=13
